THIS SINGLE VIDEO IS ENOUGH TO LEARN COMPLETE ELECTROMAGNETISM.... I WILL NEVER FORGET WHAT THIS VIDEO HAS EXPLAINED ME... BEST CONCEPTUAL VIDEO ON RU-vid......
@@TheD736 I'm talking about documentaries which are done overly showy, emotional, flashy, etc. i.e. documentaries which so not mainly focus on the information. ....Maybe you should watch a documentary about it! 😆
@@alphadawg81 Ah, yeah. It can be easy to over dramatize or sensationalize information for the sake of trying to appeal to a wider, less academically minded audience. I got assigned this video as a piece of learning material for my electrical trades course, and that to me shows just how good at showing the concepts in action it is.
We need documentaries like this. Social media is a toxic magnet on people, with the superconductors being the need to fit in, feel adequate based on material and physical attraction which in turn only sucks you in more. I remember being a kid, 8, and seeing a floating piece of metal inside this electromagnetic. I almost shit myself in sheer awe. To this day, I still love electromagnetism. I am disappointed in what social media has become and to my knowledge, so are many others.
Just as awesome as the electricity one. I might've gone on to study physics or electrical engineering if i had access to these in my youth as they demystify so much.
I have never seen such a detailed explanation in my life. This is wonderful! It all finally makes sense! Years of vector calculus based physics in engineering school don't explain the concepts well because they concentrate more on the math and potential homework assignments than theory.
I love so much these explanation so detailed for almost kids because this is the only way I able to learn after being adult and not learnt at school. I re-watch so many times. And yet, being old make this even nice.
Despite the names popping up 6 or so times throughout the video, this was well explained. I have a better understanding and more knowledge to use in my own experiments. However, my search for knowledge in magnetism, electricity, and propulsion is just beginning. Thank you for this amazing video. I may have to start a science channel just to teach people what I have learned.
Hi Im interested in truth about EM field. I think ppl in power hide the truth I think science leave us a pale explanation of the mecanism of electricity/EM. What do tou think about the fact that fluid mecanisq equation are quasi similar to electeomagntisme equation. Eleteicity is a fluid ? I believe it is. Ether is a fluid. Nasa lies about our universe and earth. I think we live inside a EM field and the sun/moon rotates its center. Sun/moon rotates the center of the toroidal vortex ring. Sun heats and moon cools look for thermomether under moonlight vs moonshade experiment. Do you think EM field is in fact same as a vortex smoke ring torus field Look at pictures of vortex ring. There are layers. Look at hurricane anatomy. Same. Layers of hot embeded in opposite col layer. Look at dan bergerud vortex ring experiment showing behviour identical as light (interface refraction/diffraction/reflection) Electricity=ether=fluid. Coil = vortex ring. Magnets do have a vortex Coils have north and south. Shape of the earth is lie. Astronauts/Nasa lie. So you cant figure out true mecanism of magnetism. Hidden knowledge. Shape of the earth reveals true shape of magn field : toroid. Sunlight hit while moonlight cools. Sun and moon cercling in the very center of the torus doughtnut ring. Hurricane again cold and hot layers. Look for anatomy of hurricane in google you will see truth. www.google.com/search?q=hurricane+anatomy&client=ms-android-samsung&prmd=inv&sxsrf=ACYBGNQRyujFKcdl5e_LpObjgCNw8zUMFA:1570896532951&source=lnms&tbm=isch&sa=X&ved=2ahUKEwi37szOjZflAhULyoUKHSjfDAYQ_AUoAXoECA8QAQ&biw=412&bih=751&dpr=1.75#imgrc=NuHQNwE5kRV3-M Smoke ring = water ring = ether ring = EMfield images.app.goo.gl/SKqQvcMQjnnnx14u7 images.app.goo.gl/L2P73inz13JZomh79 In electriciry + goes one way - the other Same with hot and cold layers Look rank hilsh vortex tube. Look at Leap frogging phenomena. Look at Dan bergerud masterpieice of understanding vortex ring behaviour same light with interface water/solvant showing diffraction/refraction/reflexion. Must watch Nature shaped as donut torus vortex. Trees, nuclear mushroom, plane/birds wings virtices, jellyfish etc Thanks
550 bc to 1050 to figure it had a direction. Another 500 years to move a wire across to get a voltage. Thank God that Petrus P. found the magnetic field. Magnetic field is holding it , not gravity. Excellent vid.
Thanks so much for sharing this; it is a great supplementation to text books. The animations help clarify subject matter in a way that is extremely difficult to do with a dimensionless page of information in a book. Why aren't there productions like this on airing on TV these days?
This video by far is the best explanation of electricity and electromagnetism. The problem with education videos these days is they try to make it look interesting and catchy trying to awe the audience but often misses out to explain the very concept. This video can be benchmark for how exactly to explain physics.
Love these six 10 minute videos. I have my students clap to the music at the beginning and end of each one and have them shout physics when the music at the end ascends to a higher note and stops. They learn from the videos and love the before and after rituals.
Most people get confused when it comes to direction of flow. I was taught to remember Glamour. That is GL - for generators left, and MR - for motors right. This is used when you're considering current flow from a higher positive potential to one of negative lower potential. As shown elsewhere, electron flow is from the negative lower potential to the higher positive potential so the left hand rule is correct when you need to consider the flow of electrons as opposed to conventional current. Anyway nice primer with a history lesson.
Thank you very much on the fact that physics and chem at high echelons focus mainly on math.Secondly,passing exams and obtaining qualifications to be armed against poverty.Such detailed knowledge is overlooked then the energy crisis is continuous because many super brains can't invent.
+Tech Tins That's a good question. Why can't people actually explain this in better ways? I'm going to share this knowledge with others so I can retain it better. I also have a few ideas for my own experiments. I want to create propulsion system that can lift an aircraft into space using electromagnetic energy. Screw fuel...fuel is so primitive.
+craftertflat TBH this only scratches the surface and is aimed at high school students. To get a fuller understanding you'll need to study advanced vector Calculus. But this series is still a very nice introduction to the general concepts. Which is why it is so good. As there are very few good introduction texts on EM Theory for children. Regards propulsion systems. The only aspect of EM theory that can provide propulsion through air are electric motors with low weight but high energy storage batteries. With jets and planes it is possible, but not rockets as they require huge amounts of thrust over short time spans. No batteries can't provide energy at that rate.
Basic calculus will give you a good understanding. Then you can go deeper with vector calculus if you want to. But if you just want to study electronics then basic calculus is enough.
wow really good video. I never understood before how motor and generator work. These animations and descriptions made me understand about them. Thank you very much for sharing this treasure. please post more videos like this.
wow. excellent retro piece with all the period attributes. From 1987, one of my favorite years - cue Electric Blue by Icehouse. the animator must have had some fairly thorough background in the subject because they got it all right even down to the brush location.
Ditto what Sean Little said! For me reading how it works would put me to sleep and I learn nothing. Seeing an animated video on how it works will stick in my brain. Cause us men are visual ya' know.
I'm shocked by how un-educative toda's videos are compared... even the extremely "informative" youtube channels (and there are few), does not get close to this level of clarity and pure info. No bullshit attractive gestures and unnecessary over editing, pure intellect.
I watched it several times and I love it... Sound and visual effects are very inspiring, enough to let one catch better that old/prime sense presence of magnetic fields. New vids don't give that insight. They just are stupidly friendly and misleading.
At 45.36, it is wrong to say that the change of magnetic field induces a current in the coil as it will only do that if the coil is loaded with an external circuit. In an Alternator or a Generator it is wiser to say that the change of magnetic field will induce a VOLTAGE IN THE COIL. and not a current. There is a current only when there isa load so first the voltage is generated with or without the load and then if there is a load the current will flow because of the voltage and the load together. If there is no load there is only a voltage at the terminals of a generator or an alternator.
God bless you man million times. Never watched such a great video. Several doubts about electromagnetism got cleared for the first time. Thanks a ton. Please bring more videos on physics
wow, u r the first person i saw in the you tube, said the subject with the atomic levels i like and love u please make a lot of more subjects like maths and chemistry and physic please sir i beg u, but one thing i did not understand in this video is why current is not produced for constant magnetic field and why each tiny electron is acting as a small magnate, if any one know please post the link of the web sites thanks u sir such a grate video
THIS IS VERY OLD INFO FROM 150 YEARS,THANK YOU ANY WAY ,NOW WE NEED NEW BREAK THROUGH IN THE SAME FIELDS,LIKE EFFECTS OF SHORT RADIO WAVES ON METALLIC OBJECTS AND WIRE CARRYING CURRENTS,AND DIRECT ENERGY PLUSES
+Neo Korben Its a very good introduction for high school kids. Hence no maths or advanced stuff etc. Which is very sensible for any high school education.
I remember watching and understanding this whole video in !2017! lol, this was the beginning of my learning in the field of electromagnetism, first step.
+Andrew Vanderschaaf --- hmmm... so you stop short of the spark when your right hand gets tired! ...or is your plug a one handed type only! ...o! I see... you're a leftie! LMAO! donk!
+Andrew Vanderschaaf --- on a better note, I use the right-hand rule and each and every time do the Franklin in me head to match this world kludge. (oh yeah there is rhyme and reason to put oneself thru such torture a lifetime). Just like QWERTY, kudzu, lady-bug killer-bug, ... many more. But I am not sold on the flow thing... I think magnetism is a deflation/inflation compression/decompression thing like a basket ball under a driblin' effect rebounds to it's pre-dent state immediately with a cubic(or more) exponential curve. ...a wobble, a ding and dents dance! Thus at the sub-atomic level, it is an oscillation, rather than a flow in the classic sense as there appear to be a barrier between those 2 realms(no-one has yet unified them) and why Quantum-this-Quantum-that lives its own physics versus classic physics. Dinnnnnnnng! ...and why I am nick-named DingBEN... I am the one who thumped the Universe long ago and sent it in a massive magnetic ripplin' wobble! ...ripples to be experienced for eons to come. hmmm! ..so also says your avatar! LOL.
Wow, 1987 had CG? I'm more impressed at the budget they had to do this. Must have been a fortune since CG was only getting started via the Amiga Computer.
If you're a teacher in New York State and are considering using this video as your only form of lesson please don't. And if you do, please don't give labs, tests, and homework that only consists of regents questions, if you do your students will have no idea what they are doing and most likely will fail or barely pass because this video has nothing to do with any of the questions on said tests, homework, and labs, thank you.
I see an (error in perspective) that can cause confusion in "The Motor Principle." Please review video illustrations from time index [28:17] as you would view a gear and [30:40] as you would view 2 gears. (Same direction) of (rotating magnetism) is (not the same) as stated in video time index [30:40]. (Between wires), they (appear the same) like (cars on a highway). You will understand clearly when you use the (law of gear rotation), (clockwise rotation) with (wire electric flow) towards you and (counterclockwise rotation) with (wire electric flow) away from you. Gears rotating in the (same direction), would (clash as opposing forces) between themselves. As with magnetism (opposite forces) attract. Gears rotating in the (opposite direction) of each other would (not clash) together as having a (unity of force) between them. In magnetism, (unity of force or same polarity) causes repulsion. Note, In closing: a (person) driving a car (as the magnetism) flows, may agree with the video, but (gears) moving the car do not agree with the video's perspective. Conclusion, Formula: Between 2 wires, with (Same) electric wire (current flow direction) and (same) magnetic (clockwise/counterclockwise rotation) = attraction. Important, understanding of (how gears work), required. Anyone that doesn't fully understand (how gears work) may find it extremely difficult to understand the true perspective I have revealed in criticizing this video. Thank you, for the opportunity to view this amazing, outstanding and informative video!
14:00 What the hell are they talking about "left hand rule", it's right hand rule that shows the direction of the magnetic field in relation to current flow. Strangely enough, the diagram they show is actually correct, IF there was such a thing as the left hand rule (and there is but not like the one they show) and IF the "direction of current flow" is considered to be the same direction as the flow of electrons (which it is in reality but conventionally it's the wrong way around thanks to Franklin).
I think that you are correct... their Left Hand Rule contradicts the Right Hand Grip Rule, and their Flat Left Hand illustrating the deflection of the wire contradicts Flemings Left Hand Rule, which has the current flowing in the opposite direction for the upward deflection of the wire.
@@robinhill5387 It's because they are tracking ELECTRON flow, whereas the right hand rule uses CONVENTIONAL current flow which is tracking PROTON flow... in the end, it is the same result.
fascinating, brilliant production, entertaining, enjoyable, but more important education at its best,. spoiled a little, I thought, by dreadful and monotonous sound effects. The video would be quite exceptional on its own, but a minor point and thank you very much for the outstanding production
When using conventional current flow as conceived by Benjamin Franklin which he thought flows from + to - we use the right hand rule. But since it was found that current (electron current) actually flows from - to + we use the left hand rule, so all polarities and directions of electromagnetic fields still come out the same regardless of which current we use as long as we use the right hand rule for conventional current flow and left hand rule for electron current flow. Therefore we do not have to change all the published work on this subject. Almost all electrical engineering books to this day still use the conventional current flow (+ to -) and right hand rules.
Thx Doc ;-) Anyone : Could the part showing the solar wind with positive stuff deflected right by our northerly mag field, negative stuff deflected left, be part of reason for Earth's rotation in that Earth is positive, pushed on right by positive solar wind repelled, pulled attracted on left to negative solar particles. ?? As well as what keeps our core magnet charged. ??
+clint beastwood Yes me to. They used very few blocks to save on CPU and so it always looks minimalist artistic. Very cool. They should do modern cartoons like this. In fact this is why I think Lego Minecraft is so popular as that uses very similar low res graphics.
Another thing for thinking? What if the coil is long and wound in a bigger loop? According to this video and mainstream physics the H field will be in a circle following the big loop (like that in the center of the coil showed in the video, but curved following the bigger loop), but, if we contemplate this from farther away, same theory as above, the current will flow slower in a big loop (we don\t 'see' the curls of the original coil anymore, a current is simply flowing ON THE SURFACE of a conductor which is bend in a circular pattern at low drift speed, does it sound familiar?), so the H field induced by this 'slower\ current will be perpendicular to the loop/s plane in a direction i dc which what hand one determines, important is the directions of the H fields induced by THE SAME CURRENT can be at 90 degrees, depending on the viewer\s distance to the system! But according to the one and only Mr Einstein the speed of light is not depending on the reference system, electrons flow at that speed, so there can\t be a 'slower" current! Weird or what? FOOK MAINSTREAM PHYSICS, only half truths and LIES! Only explanation can come from different speeds that electrons can have, Tesla even proved that, but that\s another physics!
at 33:30 according to Fleming's Left Hand Rule force should act on a wire pushing it up not down. Thumb - Force Index finger - direction of Magnetic field (from north to south) Middle finger - direction of Current (in our case is towards us) any comments?
the current flow shown in the video is the 'electron current', its direction being same as that of electron flow... for Fleming's left hand rule, the middle finger should point in the direction of conventional current flow, which is opposite to the direction of electron flow... so, in this case, it will be away from us...
