How do Magnets & Magnetic Fields Work? 

One of the BEST explanations of magnets. & magnetism And it's humbling that we don't know everything... yet. Why from high to low energy? Why do electrons have a spin attribute? More research needed. Hopefully one day, there will be an explanation - Noble physics prizes are waiting.

You are a walking.. talking encyclopedia of knowledge. Thanks for sharing

this is so much better than 10 min videos that don't go in depth. how else are you supposed to understand a complex concept like this?

This is a very good demonstration of how magnetic lines couple together to form closed loops of a magnetic field in the air or in space. Once the lines are formed/coupled together and everything stabilizes, the lines are coupled together without moving from pole to pole actually. And that is why we saw steel filings being coupled and attracted to both poles simultaneously. You did a very nice good of explaining why the fields are generated within each atomic structure and magnetic domain. The angular rotation of each atom's electrons is random, until the magnetic field is introduced to see its region of magnetic influence. Thank you for helping young people increase their knowledge of physics. QED

absolutely superb lesson sir. You explain things so well and understandable. I am so much more interested in science and its all down to you.

I’m 72 rears of age and I loved your presentation. Yes I made it to the end and I’m going to watch it all over again. Thanks for being such an enthusiastic teacher. It’s cleared up some of my own questions and needless to say brought many more questions I need to answer to the forefront… isn’t science wonderful😄😄😄

Sir, you are utterly gifted when it comes to teaching. Thank you so much for taking the time to teach us without leaving gaps in the flow of information, which so often fractures the uptake of information.

Outstanding explanation of magnetism and how electrical current and coils create magnetism. I wish struggling physics and EE101 students everywhere knew this video was out there available on youtube. This is a better and much more understandable presentation of the subject than any professor I ever had. Nice tie-in with electron spin and magnetism too. When I went through college I could work the math but never really understood what it represented. After watching this video it finally all makes sense..

I've been waiting for this! Hoping for more lessons about electromagnetism

Great lesson. Good blend of theory and practical. Please make more videos like this.

I'm an extreme biology nerd that had trouble during the physics course. I just wanted to say thanks for making this. It was very interesting and helped me get a better grade. I can still proudly say that I haven't failed any classes thanks to you.

THANK YOU... SIR...!!! You have done a great teaching...to connect all the basics we know about this PRAPANCHAM... and took us far beyond...!!! IT IS FUN AND WISDOM...!!! ENJOYED VERY WELL...!!! THANKS AGAIN...!!!

I've been fascinated by magnetism lately. Because it already is an invisible force that can easily explain why the Earth's magnetism could be the source that's turning the constellations through an invisible axis that makes a vortex which creates our gravity. Especially when you see how quantum locking works. It's just fascinating stuff.

Great demonstrations and explanations! Really appreciate your time and efforts. Thank you.

I’d like to know the brand of your microphone. Good quality there.

I like how you invited energy to the party. That’s the thing that always make magnets seem like magic things with endless energy.

This is real magic🎉❤

I am a Porter but I love science talk , I allow myself to give students an advice to review what Richard Feynman said in this part from 1:40:28 to 1:41:20.

Now get the most expensive rare earth magnets, bolt opposing sides together, weigh them and find an equal weight. now drop them from a few stories and see which one lands first. Love the channel btw cheers 🥂☺️

You're so amazing teacher everyone would love that just the way you described it incredible teacher!!!

FOCUS ON THE CENTER FIELD>>> it will blow your mind..

Amazing video sir. Thank you for illustrating everything so clearly. I'm very interested in the theoretical physics of Electro Gravitics and Over Unity energy machines. I'd love to see you do work on those things.

If all teachers were as good as you this world would be a better and much different place.

You are "the" genius tutor. No others could be that perfect. I hope we have you in other subjects

Outstanding explanation of magnetism and how electrical current and coils create magnetism. I wish struggling physics and EE101 students everywhere knew this video was out there available on youtube. This is a better and much more understandable presentation of the subject than any professor I ever had. Nice tie-in with electron spin and magnetism too.

Very well done! As you mentioned, we truly don’t know what’s happening at the quantum level, but models help our feeble minds to come up with calculations to describe our universe. I believe that magnetic field lines do not exist. The magnetic field is continuous throughout, dissipating as it extends outward. In other words, with the iron filings, one would believe that in between the lines, there is no field. When actually, each iron filing has become a magnet repelling another iron filing in its next concentric circle. Also, when looking at an electron’s magnetic field, you can use the left hand rule to show the direction of the magnetic field. Again, great discussion Jason of this complicated topic. 👍

Jason, I am 69 years old man and I have never been so fascinated by science before watching your videos, now I am beginning to understand. You are actually reversing the dynamics of the universe by going from complex to simple. Thanks for offering your talent.

Juggalos wish to know your location

I really like the way you explain these concepts. I can just see Michael faraday doing the same things amazing children. They didn't need the math, but the evidence is locked into their minds when they get in the physic of electricty. Thank you, I enjoyed it.

At 15:42, The North Pole of the compass is pointing to the south of the magnet. So why don’t we correct it, that North pole of a compass points to the south magnetic pole we’ve been mistakenly calling North Pole. Our bad

Jason, I still believe you're the best to explain things despite no one seemingly can perfectly explain to me how permanent magnets work on the subatomic level. The best I could comprehend about PMs is that once you harden carbon steel it becomes magnetic due to the carbon atoms (more the better) locked in its molecular structure that retains magnetism even after removing the magnetic field that created it (hence the reason screws stick to the tip of screwdrivers). This is only valid for carbon steel, not a proper PM magnet, although this concept might apply to them the same way.

Your video is good, but I think a better title would be “ How do magnets and magnetic fields interact “. To explain how it works is better left to higher education courses . Spinning electrons , or anything about quantum mechanics and string theory would be another video. It’s like trying to explain how all electrons are exactly the same. Like puzzle pieces wanting to fall into a perfect form.

Excellent presentation. I think it is worth considering at 1:7:04 that, as your arrows show, the external field of the solenoid does not cancel but the additive effect is diminished by the reducing flux density, and thus tends to zero in the ideal solenoid. If the external field did cancel every case would behave as ideal.

Violent Jay sent me here.

Let me share a few facts, I've been a Ham operator since 1959 as a general class operator I designed and built all my equipment (the TUBE days'). You have a good understanding of inductance!! I agree with all your findings. BUT!!! I want to expose something you can get into and it's going to blow your mind. JUST LIKE TESLA SAID look for things you can't see!! So, let me introduce you to what I refer to as the "B" field., I'm sure you know that there are three elements to any AC or Radio wave traversing space The oscilloscope only shows the two base elements, the positive and negative parts of any radio signal "BUTT!! The fact is it's the centerfield of a magnet that pushes the signal out whether it be AC current or a radio signal same thing!! Her's what I want you to learn: the centerfield of a magnet is by far the most powerful!! FACT! I refer to it as the "B" field, for a good reason it's much more complicated, Here's just a few facts: #1. If you tap the centerfield of a magnet (IE: the "B" Field) on any none Metalica item, it will lose weight. #2. If you tap the centerfield near a trickle of water, it will repel the water!! #3. If you vibrate the center field into a granite rock it will not only lose weight but also be very workable, what basically happens at the correct frequency the Quarts in the rock will reorganize. #4. The center field of a magnet is multi-dimensional. Once you start to see what's going on

Great lesson! I would love to see your Iron fillings experiment on repelling and attracting magnets. Am I correct in assuming 2 opposite magnets when attracted together form one larger magnet?

I either didn't understand some of what he said, or I don't think his explanation made the best sense. I'll have to watch the whole video over again. But a great job still.

TKS. Maybe this explains why our galaxy---and 12,000 surrounding galaxies are headed for the "GREAT ATTRACTOR". We'll pass in 220 million years.

Magic! Its genuinely hilarious how much magic (and by magic I mean electromagnetic radiation) that bombards us day in and out. Orders of Magnitude more than 30-40 years ago when there wasn’t so much autism… wonder if there’s a connection?

Excellent. More importantly, those that want so badly to have firm, definitive answers for every baseline why...why? Show me a universe where all the minutia is known and I'll show you a place where it would be miserable to live. The thing that is important/relevant for us is pragmatism. We observe the tendencies of how the universe gets on with its business and we embrace that as our way forward. Science doesn't need absolute, fully sussed out truths to go about its business. In fact, science expressly works only under a rubric of tentative truths. That's unknown by and/or lost on many.

I rather like this explanation of repulsion/attraction between magnets by virtue of energy density in space . True , it doesn't satisfy , maybe in a way analogous to the way Newton's law of universal gravity doesn't satisfy certain questions , but it nevertheless leads to useful predictions . When you were talking about magnetic field energy densities at points in space locally , I was thinking about springs , and about the energy density of the electric field between the plates of a capacitor . And as can be demonstrated , a dialectric will be sucked INTO the space between the plates which serves to lower the energy in that locale ... things wanting to be at a lower energy state .

I understand how to spill water on magnets. What i want to know is sir, how do you out on ... your PANTS?

I will never look at a solenoid the same after listening to you Thanks for the great info.

Thank you very much. Amazing presentation.

One of the best science videos so far. I know it's not easy to create this kind of video and the time. Thanks so much sir.

What a great video!! Thanks!!!!

It's so well explained that I understood every single aspects. Thank you so much. I love it. Subscribed.

Whenever you're handling neodymium magnets take care never to let them slam together because they will break easily. they're quite brittle. regular magnets probably could break as well but definitely neodymium because they're a bit stronger and they will probably slam together a lot harder

Thank you so much for this you’re a great teacher.

Great video, Thank You!

Thank you. Watched your video several times. Would have been good to have it when I was slogging through engineering physics. I and my fellow students were buried in calculus, not having physical models for the phenomena we studied. Thanks.

So clear explanations. As an EE it is like music to my ears. It refreshes the concepts in a limpid way Thank you and God bless!

Excellent explanation! when I was a student I had to read so many bookss and cost me a lot of time to have a real picture of the physical phenomena. Now Jason, in less than an hour, explains everything so clearly!!

Fantastic work. Amazing. Thanks so much.

This guy is amazing. I've learned so much from him over the years. Thank you, Math and Science.

Jason ,thank you very much

Magic laylines coming from lode stones yeah?

Cool dude! This is the Science teacher everyone needs! ☺️👌

I think you explaned it very well but I am even more satisfyed with that you admitted that it is probably just the functioning of it you explaned and not the total truth. I am especially happy with that you explaned magnetic attraction in a way that is actually a pushing effect. It is just like that vaccuum doesn't suck. It is the air aroud that pushes things into the vacuum.

A very interesting and useful lecture. Thank you very much.

Excellent! Can you do this?: Put a normal bar magnet (straight line) down vertically, then bring a piece of non-magnetic steel or whatever next to the North Pole. Have it lay on the page also. Once in the same line as the first magnet, once at a 90 degree angle where the first magnet bisects the second, and once where the first magnet attaches to the end of the second (but still with the second at a 90 degree angle). And do the paper plus iron filing thing on top at each of the three configurations.

ok ok ok ok ok

Wow nice explanation thank's sir

we'll delve into flux density, which describes the strength of the magnetic field in a specific area.

Excellent lesson. I was planning to make speakers and before that I wanted to learn magnets thoroughly and I am so glad that I found this video. Keep up the good work

Great class for anyone interested in electricity such as myself!

You sir, are absolutely brilliant. Thank you. I'm an electrical engineer, this is by far the best lesson I've ever come across. 👏👏👏

i want to see the magnetic field of a magnet via diamagnetic particles for once. the convention is to use ferromagnetic particles, but diamagnetic might be interesting.

That was impressive explanation thanks for your time and Passion and patience,,you are suburb.

Bravo.... Thanks for the very informative lesson. Science is awesome, even more so when its easily learned. Well done...

magnetism is just dielectric acceleration towards a mutual null point

Buenas noches: saludos desde Argentina, podrías poner traducción de todas tus explicaciones en castellano? todo sobre energía punto cero, Unumpentium 115 antigravedad etc

I was hoping you were going to explain why magnetism occurs in the first place or why particles have a north and south pole to begin with but alas the mystery remains... maybe one day we will understand

I am confused if someone could help clarify. I understand that the loop of a magnetic field must close, but why does the magnetic field of a current close on itself and not into the wire? Does the magnetic current of a wire even have a north and South Pole?

Amazing!

1hr and 42 minutes and not once did Professor Proton mention that the North Pole is positive and South Pole is negative. Electrons are negative and are attracted to positively charged metals and the reverse is the hole flow which is the opposite and attracted to the negatively charged metals. Take away an election creates a hole. Magnetic fields mimic electron flow which is how inductive transformers and motors work. This also explains how you can charge your cell phone without plugging it in or bladeless fans can blow air around. Interesting how the compass is attracted to Earth's North Pole but attracted to the magnet's "S" Pole. That means Neil DeGrasse Tyson is right, Earth's North Pole is actually the South Pole. Earth's North Pole is actually True North Magnetic Pole not a Magnetic North Pole like Professor Proton called it. Technically it is the "magnetic" South Pole. Then there's the "geographic North Pole which is the axis of which the Earth spins. Welcome to my world.□ Sorry Professor, I had to. Oh great, Faraday's Left Hand rule is not referring to the right hand professor. The right hand rule is Fleming's pertaining to thrust and the middle finger is current flow and the thumb is mechanical direction of motion.. Since you say the thumb is the current flow then it is the left hand rule of Faraday not Fleming. Fleming is referring to a mechanical movement which can reverse the lines of flux like your picture. That means the lines of flux in your drawing are circulating the wrong direction if you mean current flow. Now you say your thumb is hole flow so your drawing is correct. Congrats. Never the less, it's still doesn't negate the rule is Faraday's Left Hand Rule for current flow, not a right hand rule when the thumb is the current flow reference. Oh too bad, you were so close.

(work) is one of those bad four letter words. I feel it should be called "pleasure learning" or something along those lines. !WARNING!-The joy of solving mathematical problems with ease,is an addictive pleasure.

Nice lessons and more helpful and deep in content

Hi you had mentioned that when we keep 2 bar magnets with like poles facing each other, the middle space between these 2 magnets will add up to a strong or high energy state and since the universe loves getting from high state to low state, these 2 magnets repel... But isn't that space a neutral point? Coz the north poles of both these magnets have equal magnitudes but opposite direction, they cancel out. Plz clarify. Thx.

Yoy HAVE to believe in a CREATOR. High to low is an absolute of the kniwn world you say. And with conviction.

Example: what about combine 6 coppers instead of 1 copper wire and twisted. Will it have a stronger magnetic field when applied to electricity? The answer is yes but formular for the calculation is how much stronger?

33:52 how can a magnetic field be present without a north and a south pole? where is the north and south pole in a current-carrying conductor? this remains an unexplained mystery, yet everyone acts as if the right hand rule for a mag field from a wire is self-explanatory. it's because the teachers don't understand the concept. they claim, "the mag field *curls* around the wire," when in reality, the mag field has quantized radii of strength emanating from the current which is a relativistic effect of charges in motion. thus, the north and south poles are on either ends of the conductor, and the magnetic lines viewed are actually connected from the conductor's ends, not circumferentially around the wire as claimed by this guy and all others before him.

You really are sheer brilliance in the making literally an Absolutely Brilliant teacher man seriously I can't get over your style n grace n powerful clean clear concise CORRECT way of teaching man seriously I'm blown away as I landed on this video and I'm like 😮 all the way through and I never admit things like this but you are truly brilliant may you always be blessed this way hey just to say the only other teacher I've seen like you was a maths teacher I had aged between 9 to 10 etc Brilliant 👍 natural born teacher if this is coming naturally which I think it is Bless You and may you Teach on for many many many more years 👈🏼😮👍 ....edit... PS no homo

Thank You Sir, I have a question about magnetic lines of force? Since LIGO found and proved the Graviton, and working on Alien technology or the re-engineering of it. Working also in collaboration with God Jehovah, and Lord Jesus is the Christ, they informed me, or instructed me that a Graviton is about 1/100,000 the size and strength of an electron! In electro-gravitics 100,000 gravitons fill the positively charged electron "HOLES", + side of a conductor, creating a vectorized gravity force (not ant-gravity). Same with stars, planets, even a black hole. Question, is there another particle, at least 1, between the size of an electron, and 1/100,000 smaller creating magnetic lines of force. Then can a magnetic field, or those particles be in the shape of a tube or tunnel, with photons, and gravitons held within creating "beaming", all having smaller or partial charges +/-, and energies, by themselves. We have never made or have a "microscope", that can "SEE" that small, yet? Amen?

I'm having another idea, with God, Lord Jesus is the Christ in my thoughts, how's Mrs. Debbie, my wives??? Really though, Alien tech again, 1 box activating another box, with no wires, or fiber, I found can be focused magnetic fields. But with current changing a mag-field, and mag-fields producing current, can a magnet be used or modified to activate the base, or gate of a transistor, or can a transistor itself be modified to use or activate magnetics, or the particles, reason being, is if every transistor in a processor, used magnetic fields to activate, or switch it, instead of electrons, there would be almost no breakage, no friction, wearing out, or heat production, conduction? I wasn't able to "SEE", inside of the "BOXES", BUT faster, more powerful, computing, and communications are seeming possible, and knowing, believing, with God, all things are possible, only in and through Lord Jesus is the Christs' name, who was resurrected, already? Yay Yay or Nay Nay

I have been watching several videos on your video plug several of the gaps in my knowledge

I’m not convinced, I feel you didn’t explain what magnetic fields are. Or did I miss that part? From what I understand the electrons don’t actually leave the material, or do they? Like I understand that gravity curves space time. But after watching your 102 minutes video I still don’t understand what a magnetic field is. Why are there gaps and empty spaces in the field? What gives these field lines a direction from N to S? When you show N-N you do a lot of explaining but I miss the part that’s actually responsible for them to repulse. Like do the electrons collide with each other? Is it space time that curves? What is the “material” of a magnetic field? Simply stating that there are lines going from N to S does not satisfy my thirst for knowledge.

Are you guys aware Lord Jesus is the Christ has been back in the clouds, at least once already, just as He said He would, in Mathew, I believe, point is He, Lord Jesus is the Christ really did walk the Earth, in the flesh already, about 2000 years ago, came out from God, was brutally friggin murdered, and also was resurrected by God Jehovah, our Father, already too, just saying, Amen? Yay Yay or Nay Nay

This is awesome and all. However, anyone can show yo what a magnet is, what it does. BUT, NO ONE can tell me what a magnetic field IS !!! What makes up the field? Seems to me, there must be something all around us interacting with nothing until current flows. Or electrons move, we may never know the answer, seems it is magic! Possibly it is the same force keeping the electron in its orbit. The tether attaching it to the atom... being free to interact like two free hands reaching one north one south, (left or right) I don't even know how this would be studied, we can't see that small. If there is something 'dark' all around us creating to nothing except electrons in motion, it's basically impossible to study . You can't just pick up electrons and play with them! So what are magnets and their fields really??

El imán es un dispositivo de energía libre, porque atrae los metales gratis y para siempre, ejerce una fuerza siempre gratis sobre el metal, que es un trabajo físico (provoca un desplazamiento en el metal) medido en Julios.

Brilliant explanation Jason. I stuck like glue to your video to the very end and I am most grateful for your determination to explain. This was a subject that I was interested in at school, but back then in the 70's/80's I never really got to grips with it. Needless to say I've ticked the subscribe button! Brilliant props. Wm.

Thank You again Sir, if there are small particles, I'll call them magtiles (magnetic-particle) making up magnetic fields, then electrifying a bar magnet for example, 1st would bring all of the electrons to a higher valence shell, but if it is emitting mag-particles, it should increase those, creating a larger field. The more power, wattage, the stronger the field, until we, it could repel, lasers, masers, bullets, whatev? But more than that, Iron, Fe for example, is much lighter, stronger, workable, less brittle than Lead, Pb, space radiation, or electrical shielding, for deeper space travelling, space craft skin, or electronic component shielding. Now a magnet, next to a coil, or inductor, might be able to induce a current +/- into the base, or gate of a transistor, both stronger, and faster, with less heat, or friction, parts that last longer? Yay Yay or Nay Nay

As the earth was forming if you consider density of elements like copper, a layer of mercury between gold and Thallium or lead, plutonium, ..... couldn't the planet be acting like a massive electromagnet rather than permanent magnet? Kind of like a revers centrifuge.....

Science can be used as a tool or understood like one would approach Love, I mean it is often a child who has seen nothing that would be amazed by gravity, the wetness of water, magnets, you name it, however as Science turns into Technology and then into Economics it seems the Adult has largely lost the wonder sitting in the Science no longer imagining the possibilities of reality as a child but living it, and I regrettably say that the general view isn't clear, most people would never experience how magical life could be since the child can't go to work with them the child is left behind and forgotten. A Materialist would argue gravity holds my sheep flock glued to the ground, I know nothing of gravity but I know I can grow fat on eating and breading my sheep, so there is where I will expand my horizons....So going after the next house, next status, next economic step has little to nothing to do with the underlying magic and mystery, in fact economy is a pact between man and man where nature is a pact between life and death, in all the forms it takes, with humanity sprinkled in, one we gave birth to and the other gave birth to us and just like a start and end, top and bottom it's good to know which side is which. So today we may say Current flow and Electron flow should be kept separate, but who says it will be so in the tomorrows that come. A big factor would be interest, magic, wowness, words don't do the experience or feeling justice and as such we can't directly point each other to the magic but hope the magic may magnetize us closer to "God" or "The higher wiser self within" and as such we can get more clarity on reality. The thorny and hopefully rosy point I am trying to make is that if the body of reality, our planet, life, money, what have you is used purely functionally and economically, and the ambiguous magic every child is born with, to discover and understand, is not nurtured, the inner child will wither and only a functional shell will remain. So may Culture evolve towards fuller beings in conclusion.

no energy from magnet but from vacuum...space time locally distrurbed = magnetic field

You keep saying that the field lines go FROM north TO south. Why is there a direction? What does that mean exactly, and how do you demonstrate it? Obviously they form a loop between North and south, but why not from South to North?

Superb explanation. I dont know shit about this things. But i love science. You are Great for letting me understand a little bit of magnetic fields. That i would never understood one my own. RESPECT.

Thanks!

How Do Magnets and Magnetic Fields Work? Good question. I like this video because it provides a lot of knowledge. Always success "Math....."....Pekalongan, Central Java, Indonesia On

Another Excellent lesson , Jason.
