Making music with ELECTROMAGNETIC FIELDS?! 

i swear, this dude can pull some sick tunes out of pure silence

Hey Andrew! Electrical Engineer here, I thought I'd help explain the question you had in your video. Electromagnetic fields are invisible areas of "influence" that magnets and electrical circuits create. Fields are *typically* invisible, and can effect objects without actually touching it. A really common example of this is gravity, no matter where you are on Earth, you are always pulled towards the ground. There isn't any physical object that is pulling you downwards, it's simply the gravitational field that is attracting you. Electric fields and magnetic fields follow a very similar principle, and work with one another like dance partners. Magnetic fields are simply the invisible area of influence that a magnetic object has. Think of any typical fridge magnet, as you move it closer and closer to a piece of metal, you can feel it being pulled towards the surface. That 'force' that you feel is a magnetic force exerted my the magnetic field. Now electrical fields are fields created by both charge (a buildup of electrons) and current (the MOVEMENT) of that charge. Here's a similar example, if you've ever rubbed a balloon on your hair and then stuck it to something, that is the effect of lots and lots of tiny electrons building up on the balloon, which then are attracted to the more neutral charge of the object that you're sticking it to. As for *current*, whenever you plug in an object that draws electricity, electrons are pushed through the wires. These moving electrons create a field of their own, and is the very principle that allows antennas to broadcast video, music and other information. Now, believe it or not, both of these fields can actually be considered to be the same thing! When you take a magnetic field and move it around, or change it, it creates an electric field. If you take an electric field and move it around or change it, it creates a magnetic field. We take advantage of this principle all the time to create electromagnets! Unlike a typical fridge magnet, an electromagnet can be switched on and off at any time, and we use them constantly! Your speakers especially are based around the principle of electromagnetism, and they all work in similar ways. Basically, if you take a current and force it into a spiral shape, you can create a magnetic field. Your speakers use this to vibrate really, really quickly and create sound. This principle is so useful, that we take advantage of it in almost every electronic device, and we can do some wild things with it! I hope that helps! Love your videos by the way, keep it up! *internet high five*

4 fundamental forces of nature (title speaks for itself): Gravity (ironically the weakest one, by a lot), strong nuclear force, weak nuclear force (like gravity but for within and between the atoms that make...everything else), and the one feature din this video: electromagnetism (The awesomest one). Fun fact: Electromagnetism is powerful enough to counter act or break the other three forces, so, theoretically, anybody who can control them (say, comic book characters) could tear the universe apart... Electromagnetic waves: Light. Electric and magnetic waves are literally combining (perpindicular to one another) to form a new wave and scientists suck at fancy names so they called them electromagnetic waves. Light comes at several different frequencies and wavelengths (just like sound waves...and waves in general) and pretty much any electrical device that runs current through a conducting metal will generate some type of electromagnetic wave. Since humans can only see a small range of light waves (450 nanometers - 750 nanometers makes up the visible light spectrum) we don't notice the light bulbs, phones, computers, plugs, etc. making all those waves on a day to day basis BUT when collecting data with a sensor (like this awesome gadget!) they will typically pick up noise generated from our modern society. This cool little device, instead of being set up to filter out the typical 60 Hz noise, intentionally captures the sound. Whoo, glad all those Engineering classes payed off.

Its from Slovakia, ELEKTRO-SLUCH means ELECTRO-HEARING

Gosh dang, dem electromagnetic spectrum waves sure do make me feel funny!

who else thought it was a tazer

He straight up made music with a ghost detector

Siri: Ha the audiological elctromagnetic field is so funny *static* Siri: man hes a riot!

1:54 Snapchat spectacles?

did he literally make an electro song ...

Now this... this field is real electronic music, for the current generation. You induce so much pleasure, with your capacity for making music, and I will frequent your channel a lot, because your videos get me amped up, and give me so much energy, it Hertz. I feel the power; it gets me reactive. It's a sine. I'm in electrical engineering, and I hope someone understood all my puns. Thank you.

1:19 close your eyes

This is amazing dude! congrats on finally making it! 😊😊

I'm so glad that i have this channel in my subscribe list :)

I'm going to attempt to answer your questions about Electromagnetic fields and the 4 fundamental forces of nature/the universe in as simple a way as I can. *The 4 fundamental forces of nature* The 4 fundamental forces of nature are: the strong, and weak nuclear force, gravity, and the electromagnetic force. Those first 2 have to do with atoms, specifically protons and neutrons. Put *very* simply weak force is what causes radioactive decay in atoms. It's what makes nuclear energy work. The strong force is what prevents neutrons and protons from dissolving into quarks and gluons. Protons/neutrons are a combination between types of quarks and gluons. There are 6 types of quarks and the combinations (usually in pairs of three), form all the known particles in the universe. Gluons are found between each quark, and act much like a glue that holds them together. The stongs force is what holds this structure together and actually gets more intense as the distance increases between those particles. Gravity is the least understood but most known, it is the weakest of all forces most noticeable at very large scales. I'm sure I don't need to go in depth on this one. Finally electromagnetism, if you've ever played with magnets as a kid then you've physically experienced a magnetic field and if you've ever seen lightning then you've seen electric fields at work. Any piece of metal that has an electric charge also creates a magnetic field around it; this is how electromagnets work. Also this works in reverse, magnetic fields can induce an electric charge, spin some magnets around a piece of metal and you have an generator. *Electromagnetic Fields* Any thing powered with electricity creates a measurable electromagnetic field, it radiates using radio waves which are a form of electromagnetic radiation and that is what this device is listening to. When you pointed it to the lamp the sound produced was a 60 hertz wave, this is because the electricity that comes out of your wall is a 60 hertz, cycling between 120v and -120v 60 times per second. Electromagnetic radiation is harmless it's what makes up all the light you can see, how radio works, how wifi/bluetooth works, it's also produced from our sun, and even our planet has its own magnetic field orientating our compasses north. I hope you learned something and If you have anymore questions don't be afraid to ask

Elektrosluch basically means electro-hearing, so the purpose of this device is mentioned in its name. It's pronounced [ɛlɛktroslʊx]. just 4 u 2 kno

A brief explanation, because you asked: The four fundamental forces of nature are gravity (for big stuff), the weak and strong interactions (for really really tiny stuff like the nucleus of an atom), and the electromagnetic force (for charged stuff). Charged particles that are static (not moving) emit an electrostatic field, according to coulomb's law (essentially, +/+ and -/- repel, +/- attract). When charged particles (ex. electrons, protons) move, they emit another field called a magnetic field, which makes other moving charged particles change their direction of movement (roughly). This magnetic field effect actually comes as a result of special relativity (Einstein)! So, because electric fields and static fields come from essentially the same thing, we call the two fields together the "electromagnetic field." Electronics emit these fields because they have electrons (charged particles) moving around in them. Pretty neat stuff! By "field", by the way, we mean "vector fields", basically something that has a magnitude and direction at every point in 3-D space. It's like how at every point around earth you would have gravitational vector pointing in the direction of earth because something at that point in space would be attracted to it. Electromagnetic fields are a bit more complicated, but it's the same kind of idea.

lmao, "you're not going to read it to me?" the struggles 😂

could you imagine if he took like every sample pack he's ever made to combine into one song

your videos are great. found you by mistake. subscribed immediately

"they sound really nice and fat" -Andrew Huang, 2017

Lmao the guy at 5:28 :D

"Ok i found this" ..... ..... .... "Your not gonna read it to me?!" LOL

I haven't seen any other RU-vid channel with such awesome and smooth editing. It's natural. It's doesn't feel like you try to act hard. Good Job

Next, make a song using one of those fidget cube things haha

well I am early,now what hmm I will make the best beat ever ba dumkababbao buaaawmmm chhhh ke ke ke ke chouuu bababombom I think that would be great elevator music

Wow that’s groundbreaking tech right there. I have an idea! What if I wind some copper around a magnet an pluck a fixed metal string over it? I bet I’d generate an electric current within the magnetic field! Then amplify that current ,and wow, my neighbors can hear my awesome zither solos!

The stickers are lsd

Lol he's unboxing LOM and then look at my name lol

This sounds so much like Watch_Dogs 2 music! :D

Imagine going outside and seeing andrew huang recording sounds with this electromagnetic thing

Bruh, not only does he make music better than I ever did combined. This dude can make music out of PURE SILENCE Honestly I think he is better than all of us people in the comments combined.

wow that's actually pretty dope techno - i love it

"Or the four fundamental forces of nature, one of which I can assume is Beyoncé!" - Andrew Huang 2017

'this is the thing' *casually starts playing quinoa balls* *scream*

Wow, love what you did with the sounds! I made a similar electromagnetic listening device out of a telephone coil and went around recording, trying to be discreet (since it looked kinda...odd and slightly dangerous with wires poking out). Thought it would be a good idea to try and record the sounds of the anti-theft barriers in a shop...but it just set them off instead and made me look even more suspicious! 🤦🏼‍♂️ Maybe I should buy an elektrosluch for next time!!

I am learning about electromagnetism in my Engineering Physics course.

CAN YOU PLEASE DO A SONG CHALLENGE WITH PENCILS?!?!

You can probably do the same thing by hooking up an antenna directly to an amp. All you need is to take a standard patch cord and attach it to two wires going in opposite directions, one wire connected to each of the two connections on the patch cord (one on the tip and the other on the shaft)

if i would see someone walking around like that is be like, gost busters? Doctor Who?

The four fundamental forces of nature: -electric fields -magnetic fields -electromagnetic fields -Beyoncé

You're basically a superhero now!

You’re so brilliant. By the way, I found you through Rob Scallon. Who I found through Sarah Longfield. Who I found through an advertisement for music man guitars that turned me onto Jason Richardson. So yeah, my list of favorite musicians is growing so fast thanks to the tube that I’m staying up till like 4 am every night. I guess that’s not night anymore. But anyway, thanks for all your inspiration everyone, yeah!

How did I not know about you already. I'm in love with what you do and I can't wait to hear more of your creations. Great work!

This is how you download aliens

ever heard noises like this in your (desktop) computer speakers just before getting a text? Same principle. The wire running down to the computer is acting as an antenna, sending the wave induced into the speakers. that's why a lot of wires have those big cylindrical chunks on them. they're called ferrite chokes, and as the name implies, contain iron in them. the magnetic field of the choke will magnetically insulate the wire, keeping it from inducing electromagnetic waves.

Whenever current is changing in a wire, it generates a changing electromagnetic field, which is essentially the same thing as radio waves or light depending on the frequency at which it is changing. That's why sometimes you can hear a 60hz (A half sharp-ish) hum from amplifiers. What you're hearing is the electromagnetic fields from the 60hz alternating current from the power lines in your house. Also your phone and computer will have a bunch of high frequency clicks and hums from the radio waves they use to connect to the internet via WiFi or 4G or whatever as well as some other noise from the motors in hard drives and stuff like that. You can even hear your cpu and gpu sometimes when they're working really hard and drawing a lot of power.

1:05 Ta ting goes SKRRRRRRA

The four fundamental forces of nature are Gravity, Electromagnetism, the weak nuclear force and the strong nuclear force. You already know the first one and the last two are fiddly atomic stuff you shouldn't care about.

Andrew I love your vids... You should do a song using only a bike. Like a bell or the chains could be useful...

You can do pretty much the same thing by just pluggin a pair of dynamic headphones (need coils inside) into a mic input in an audio recorder. You can also use a dynamic microphone - I found out that Shure SM-57 has a very sensitive coil for electromagnetic waves. OF course you will record sound waves mixed with the electromagnetic waves. So you could wire yourself a coil to a phone jack to make this better.

You are the coolest person!!! This is legit inspiring me to make music out of anything. Thank you for being you! 😄

3:22 GTA:SA 😁😁 just me?

confirmed andrew's next song will be him mixing goose sounds

Hey Andrew! Awesome show :) Electromagnetic field is really amazing thing. The whole universe is filled with it: radiowaves, heat, visible light, x-ray - all this is the vibrations of this field. And even more amazing is that every particle that makes up every atom is a vibration of this field. All the matter in the universe is an enormously complex symphony of this vibrations of the electromagnetic field :) Although the frequency of the matter particles is so high (somewhat around 10 000 000 000 000 000 000 000 000 Hz) that obviously we can't hear it, but only experience as something solid =D

That shirt made mad and happy. What a roller coaster of emotions.

Idk why but I can feel the tv on. 'On' as the tv is blank with a black screen, so like people think it's off and stuff but it's actually on. It's like I can hear the electromagnetic field or whatever coming from the tv and it bothers me so much that I have to turn off the tv. Idk, is it me?

You should do a cover of Electric Love by Børns with this and other electrical equipment, that would be interesting

lmfao 5:16 I cant help imagining dept of homeland security like tackling you and asking you what in the heck ur doing LOL

Make dub step with a door. Squeaking and tapping. It'd be cool!

This guy is lying, everybody knows that pot plants have electromagnetic fields!🤣

I'm honestly considering funding your Patreon, I would never really do that, but you do a really great job at offering rewards to your donators.

1:30 - 1:45 I have never laughed so hard when i'm alone in my house. Funniest thing I have ever seen.

A similar effect happens if you have your cellphone is communicating on certain frequency bands and is near powered speakers or a radio receiver. It's a series of beeps and staticy clicks that get louder as the phone is put closer to the receiver/speaker. Mine seems to do it when it's connected to an EVDO rev. A network. I bet that device could pick it up, too!

Electricity and magnetism is two aspects of the same force. This is called electromagnetism. Anything to do with this force emits a field and the device can pick up that field and interpret it for you as a sound.

four forces of nature are gravity, electromagnetism, the strong force, and the weak force. the strong and weak forces hold together atoms and stuff.

ELI5 Electromagnetic Fields: Things that run on electricity or strong magnetics generate an invisible field, that attracts and repels other electronic or magnetic things. The field is generated by the movement of tiny particles called electrons, which exist in pretty much everything in the universe. If something has a lot of electricity moving through it or is a very strong magnet, the electromagnetic field is bigger and stronger. Also, electricity and magnetism are the same force, just two sides of the same coin. Magnets can make electrons move and generate electricity, and electrons moving through things can generate a magnetic force as well.

This is pretty much a normal microphone, but without the tiny metallic moving parts that react to sound. Microphones work by putting an object in a tight magnet wire coil, when the object is hit my soundwaves, it moves a little bit, creating a small magnetic field that's just powerful enough to create a disturbance in the waveform of the current in the coil, a processor takes that, then boosts the volume high enough to hear, & sends is out across a cable to your computer or your headphones. Instead of moving tiny metal foil sheets, this just takes the magnetic fields that are already being produced by things, & it's much more sensitive so that it can actually pick up the fields without having the source of the field inside of itself. Some fields are actually powerful enough to hear without it though, if you take a strong magnet & hold it next to a transformer that's plugged into an electrical socket, you may be able to feel the field or hear it from the magnet vibrating (This doesn't work with all transformers though, so if it doesn't work for you, find another transformer, the transformers you want to look for are things like older laptop power supplies, you can also use a fish tank filter, those have tiny transformers that drive the motor.).

also the 4 fundamental forces are gravity, electromagnetic, nuclear strong force, and nuclear weak force

hey this gadget is really cool.hope its not too expensive.

I love those sounds and the sound turned out awesome! Definetely getting the sample pack.

You got some serious skills dude you are awesome i hope you'll get to 1mil subs very soon!!❤

I'm addicted to Andrew's content

Could you upload a sample pack for the raw sound files?

You can build one by yourself. Just connect a coil to a audio cable and feed it into a mic/line input. Almost no costs at all and lots of fun

Things you should record: laptop when booting, zoom of a camera, phone when dialing, neon lights. And what really rocks: an old analogue TV set, That LOM is basically a so called coil mic. If you're on a budget, a coil mic (or coil pick-up) with a headphone jack costs around $15.

I just shared this with several people ;)

Hello Andrew! I got a new microphone/pop filter, and I wanted to thank you for inspiring me to upgrade my stuff and practice (this sounds formal and weird sorry)!

You can kind of do this with an AM radio, too. We have an old calculator that makes a sound like a vaccuum cleaner through the radio.

In physics, the fundamental interactions, also known as fundamental forces, are the interactions that do not appear to be reducible to more basic interactions. There are four fundamental interactions known to exist: the gravitational and electromagnetic interactions, which produce significant long-range forces whose effects can be seen directly in everyday life, and the strong and weak interactions, which produce forces at minuscule, subatomic distances and govern nuclear interactions. Some scientists[1][2][3] speculate that a fifth force might exist but if so, it is not widely accepted nor proven. Each of the known fundamental interactions can be described mathematically as a field. The gravitational force is attributed to the curvature of spacetime, described by Einstein's general theory of relativity. The other three are discrete quantum fields, and their interactions are mediated by elementary particles described by the Standard Model of particle physics. Within the Standard Model, the strong interaction is carried by a particle called the gluon, and is responsible for the binding of quarks together to form hadrons, such as protons and neutrons. As a residual effect, it creates the nuclear force that binds the latter particles to form atomic nuclei. The weak interaction is carried by particles called W and Z bosons, and also acts on the nucleus of atoms, mediating radioactive decay. The electromagnetic force, carried by the photon, creates electric and magnetic fields, which are responsible for chemical bonding and electromagnetic waves, including visible light, and forms the basis for electrical technology. Although the electromagnetic force is far stronger than gravity, it tends to cancel itself out within large objects, so over the largest distances (on the scale of planets and galaxies), gravity tends to be the dominant force. All four fundamental forces are believed to be related, and to unite into a single force at high energies on a minuscule scale, the Planck scale, but particle accelerators cannot produce the enormous energies required to experimentally probe this. Efforts to devise a common theoretical framework that would explain the relation between the forces are perhaps the greatest goal of theoretical physicists today. The weak and electromagnetic forces have already been unified with the electroweak theory of Sheldon Glashow, Abdus Salam, and Steven Weinberg for which they received the 1979 Nobel Prize in physics. Progress is currently being made in uniting the electroweak and strong fields within a Grand Unified Theory (GUT). A bigger challenge is to find a way to quantize the gravitational field, resulting in a theory of quantum gravity (QG) which would unite gravity in a common theoretical framework with the other three forces. Some theories, notably string theory, seek both QG and GUT within one framework, unifying all four fundamental interactions along with mass generation within a theory of everything (ToE).

Underrated youtuber imo

What where you doing at Dundas with the electromagnetic thing XD (Toronto people will understand me)

" Hay its Lu back for another unboxing the... uh I mean ANDREW HUANG" great vid by the way

haha, amazing! Magnets and electricity are nearly interchangeable in terms of force. A mic is made of a copper wire wrapped around a magnet. Electrical generators work about the same, spin a magnet with copper wire and boy you got a stew goin'! It's pretty much the same in reverse, send electricity through a copper wire, coil it up, and boom electro magnet! Or radio, or dozens of other devices. Therefore, your basically hearing the transduction of the electrical signal into audio in the same way you'd hear a radio signal, however at a different frequency range! Electrical outlets oscillate at 60hz due to "alternating current" rather than DC direct current, so your lamp is just a 60hz buzz. But your laptop and usb devices sound insane because they're emitting EMF at vastly different frequencies! I might have made some errors in there, it's off the top of my head, but that's basically it! :)

2:59 "Will it music?" Let's talk about that! (Someone better get that reference, or I'll be really disappointed).

An electromagnetic field is an space in emptyness (generaly) that is the "combination" of a magnetic and an electric field, this means that a magnetic field depends of the electric one... In a object with "good" electromagnetic propieties, what hapens is that there is an electric and magnetic field, the electric one makes a flow of electric charge in himself, but the magnetic doesn't make a flow of "magnetic charge", so this flow is = 0. The electric field depends of the magnetic fiel... But it oposses to the way it was "originaly provocated" (V'×E"= -d'B"/d't), and there is the reason of the negative symbol; and it also depends of the time this field is being profuced. And the magnetic field, also, depends of a electric charge called J", so if there is this charge, there is, necesarily, a magnetic field. If you want to know more, see in books or Wiki the laws of Maxwell. Salut from Spain, Jorge.

An electro magnetic field, is basically the magnetic field that is put out by wires when electricity is pumped through them, its like how speakers work by creating a magnetic field that makes sound waves. The reason your appliences humm and click is because of electricity going through ITS wires, the reason your light hummed at a constant tune is because of the frequency of the Alternating current that goes through it witch can be replicated with the same frequency on a sound generator. Your device picks up these fields and amplifies them and turns them into soundwaves.

There are some really cool descriptions of electromagnetic fields in these comments. Nicely put, JetpackYoshi in particular. But just a quick one for you Andrew, and all the other music people out there: ever played electric guitar or bass? The pickups on an electric guitar also work on the principle of electromagnetic fields. The magnets in the pickups create a magnetic field. When you play, the movement of the strings through this magnetic field causes there to be current 'induced' in them. In other words, it causes electrons to flow in the strings. This current in the strings creates an electric field. The electric field in turn causes current to flow in the coils of the pickups, and this final current is the output that goes to your instrument's internal circuitry, and then on to the amp. All this noise you're getting Andrew? That's actually the reason people use humbucking pickups. In a single coil pickup, all of the other things around you which create electromagnetic fields get picked up by your pickups, in the same sort of way that current is caused by the vibrating strings. This is what causes all the extra noise in a single coil pickup. In fact, you could in theory do the same thing as you're doing with the Elektrosluch with a single coil pickup, although it mightn't work quite as awesomely well. Humbuckers solve this problem by having two single coil pickups where the coils are wound in opposite directions. This means that the signals they get from all those noisy background items cancel out- but also means that you get that same sound from the strings from both of the pickups. This sound from the two different pickups adds together, giving you that distinctive, beefier humbucker sound. So to some extent, I'd agree. Every other electro song is a liar. But at the same time, anything which uses an electric guitar or bass is just as 'electro' as this. In fact, microphones and speakers act on identical principles! Okay, geek-mode: deactivate. Seriously cool stuff! And as always, loving the music.

Essentially a really strong guitar pickup

PLOT TWIST its actually a taser

skip ahead to the part with the star in front of it if you want to get to the helpful part. ( may be undr read more) you can do some really cool stuff with electromagnetic fields. As most people know about the electromagnetic spectrum, there are many frequencies from radio to visible light to xrays, microwaves, and more. You can do many things if you know how to make a transmitter. * Ex. Wifi is made from radio waves that send info at a high rate frequency, but if you find a program to transmit audio or other info through waves lie radio or light, then you can do many things with it like hook it up to a light bulb and and have a light detector to recieve that audio or movie.

I actually just learned about EM (electromagnetic) waves today at school. Apparently, light is an EM wave. I wonder if it would make different pitches of the same sound if you put that thing up to a rainbow colored thing

What software are you using? Is is Ableton Live?

Hey it's Andrew Haung✋

i couldn't resist, i had to pause at the beginning to admire that rare opportunity :P

Electro magnetic fields are used in things like wireless remotes , wi-fi and even tvs

Listen, i know i made this comment before, but i don't know if you've seen it and me and around 500 people wanna see it too! So please, around a week ago, our bork and savior, our bork king, gabe the dog, has passed away. So in his honor, can you please make a bork remix using his borks?

I subbed ur so lit

This is great stuff! LOM has generously open-sourced the circuit of the Elektrosluch, providing circuit schematics linked from their site, and they did a tutorial on building an older version for a MAKE Magazine "Weekend Project" video. I just built my own, here in the strange future world of 2020.
