Turning Magnetism Into Electricity (Electrodynamics)

Most of our energy isn't generated chemically like in batteries or by solar panels. Whether, it's coal, gas, nuclear, wind, or water power; it's generated by magnetic induction and governed by Faraday's law from electrodynamics.

What non-scientists don't appreciate is that the entire world's economy depends on coils of copper spinning in magnetic fields.

Oliver Heaviside is the most underrated scientist ever. In school they teach us about Galvano, Ampere, Tesla and so on, but never Heaviside.
Oliver Heaviside was an autodidact (self-taught) mathematician and physicist. He coined all the terms used in AC circuit analysis, he invented vector calculus and his work changed telecommunications.
Fun fact: since he wasnt formally educated, he was in conflict with the scientific establishment his whole life

i love that you always explain words . it really removes misunderstanding.

[cedricveinstein]

Your videos should be mandatory in school as an introduction to a new subject, they usually make it SO much easier to understand a course. Many teachers know the subject, but they can't teach it. Your videos are usually "reference level" in both cases...

[IncroyablesExperiences]

I think the important thing that people often miss is that when current in drawn from the voltage source (so power), a torque is created so that it impedes the rotation. So we don't only have to make spin the rotor "once" to give it momentum, but apply a constant power at least as much as the drawn electric power.

This has to be in the top 5 channels on youtube. Incredible explanations and hysterical commentary. I think I've laughed to tears at least three times watching this channel.

[jb_lofi]

I jumped on this as fast as I could and you already had 230 views and 38 likes. Keep this up dude, you not only matter so much to me as someone that was screwed out of a proper formal education in the sciences, but I pass this stuff to my (at the moment:) 9yo nephew and use it to explain things ostensibly "beyond" his ken. You're making a huge fucking difference, man, keep going, even though it won't be immediately visible. You're not just making my 30yo ass smarter, but I use your material to encourage kids I know. KEEP THIS UP, and I'll be supporting you via patreon in a few weeks (sorry, I'm poor :C)

This is amazing! I'm studying EE, so I've already read about electromagnetism. This series of videos help me understand the concepts.

3:30 It's also worth to mention that when there is something connected drawing current from the generator, it gets harder to spin (I guess you'll cover Lenz's Law in a future video). That's why infinity energy generators don't work.

When there's no current flowing, all the force you apply is turn into motion, and since nothing is consuming energy, the coil would continue to rotate indefinitely, if there was no losses due to friction and drag. However when something is connected, creating an electrical circuit, part of the kinectic energy of the coil is turned into electrical energy. Thus if the torque applied is constant, the angular speed of the coil will reduce, or conversely, to make the speed constant, a higher torque is needed.

The Missy Elliot reference was epic! Possibly your funniest antic Nick.

[AztroG]

I wish I had discovered this channel years ago! Absolutely profound insight along with an impactful delivery that makes us viewers engaged! WELL DONE SIR!

[djsavic]

Best explanation of what voltage is... ever. I finally understand it. Thanx.

[ostapkurtash]

I am master in Electric engineering and still enjoyed every minute of this video. I guess I just like the topic and you explaining :D

[KarinTerrell-dv]

I'm 14 and I just wanted to randomly create an induction generator, and I was wondering if I could have a little help.

[philipberthiaume]

Pushing a wire side ways in a magnectic field should cause current, brilliant and very clearly explained. Now I know exactly how the relationship between current and magnetism works, great video...

[mikedvp]

Have to be honest, first time watching one of your videos I felt like they was meant to be just for kids, but now I really enjoy each one of them. They are explained so well, in such details without all that misleadings examples that are used to supposedly help us understand.

I hope you keep doing it for a long time and I expect to be one of your patreons soon. I think I may help you with spanish subtitles so I could recommend this channel to more people.

Thanks for your work!

[adamroach]

I'm taking physics, and I'm going to ask my teacher if we can watch your videos. He use to be a professor.

Video title: “Turning magnetism into electricity”

*_Michael Faraday is typing_*

[shivakarthik]

Valuable video. Explained the meaning of the equation for Faraday's Law. This stands out in another level of explanation!

[MOSMASTERING]

Essential viewing for students wanting to get into these subjects. Great explanations..
