    Casually Explained: Magnets...

    So I get why electromagnets do the thing they do.. DC current in, magnetic poles on the edge of axial coils.. Simple. We get it. It's the thing that makes transformers and relays and solenoids do the thing they do.
    BUT, explain to me why wrapping wire around an axial magnet (ea; a magnet shaped like a cilinder with the poles on the ends) doesn't induce a permanent DC voltage (or current) in the wire? Like, I get why the field lines go in a loop from north to south pole, and I get the right hand rule, so why doesn't a stationary magnet with a coil around it equal free energy? What's the "stuff" actually travelling the magnetic field lines?

      Look up electromagnetic potential. One of the things you'll realize is the path is just options for the current to travel and doesnt do so until an option is opened up for it to interfere with. In fact electrical currents can actually pass right through the insulated cables theyre being passed through. Such as power lines for the electricity for your house. The only reason the electricity doesnt escape the insulated lines is because its a more difficult option for the current than following the wire inside the insulation itself. This is why you can get electrocuted by touching insulated power lines.

    You got the right hand rule wrong, it’s for straight wires. When you coil a wire it forms a solenoid which has a similar field to a normal magnet.

    I'm a physics student and had to prepare for an experiment featuring magnetism once. We have to know the theory or we aren't allowed to do the experiment which is bad. I read the shit out of the explanation in textbook and finally came to the understaning featured in the video. But then the tutor told me this semi-classical approach to explaining magnetism isn't actually true and since you don't understand your quantum mechanics yet and we don't have the whole day I can't give you the real explaination. So you could say, freaking magnets how do they work...
