Did you skip 3rd grade (and all other) science class?
Even if you studied it, the answer boils down to “magic”.
You take these magnets, and move them around these long snakes of metal (because electrons can move easily through metal) and that makes the electrons in the wires move.
Okay, why does moving around a magnet near metal make something inside it move?
Well there’s something we call the “Lorentz force” which basically pushes a magnetic thing in a specific way if you move another magnetic thing around it
But why does that happen?
Magic
It’s all attraction between opposite charge and repulsion for the same charge, even magnetism. Magnetism is just charge in another gauge.
What I mean by this is from our perspective we view a moving charged particle as emitting a magnetic field, but if you were to move along with the particle at the same speed it would be observed as being at rest and emitting an electric field.
No it’s actually summoning demons
Idk man Jackson’s Classic Electrodynamics left me feeling like a jock in calculus.
Not really though. You can say that about anything if so. If I don’t understand why atoms exist, does that make the universe “magic”?
I mean I get what you’re saying kind of, but understanding the basics of electrical power is not the stuff of sorcerers.

I mean, from this thread it shows people kinda remember stuff from those classes, but are missing a lot. Which is understandable, people left school and didn’t use that information, it doesn’t make you stupid.
But then you think, oh yeah! I remember how to make electricity, I need copper and an iron rock! So you spend all this time trying to manufacture some relatively thin copper wire, iron would probably be a little easier to find, wrap it around and then you’re like… Okay what went wrong? Annnnd you can’t remember you actually needed a magnet and you gotta spin it.
Then do you remember learning how to store it? Connect it to anything useful? Maybe kinda, but extrapolate the first situation to every topic ever and that’s what you’d get, half baked ideas that you don’t really remember the specifics of. And the specifics really actually matter lol.
