    this feels like an incredibly simple question alongside the other threads, but i can't seem to find the answer. all i want to know is how to use an electric current to spin a hollow cylinder, such as in a motor belt with a rubberband connecting two wheels that turn the band. any help appreciated!

    Are you asking how an electric motor works? I'm sure there must be something on the interweb. Have you tried googling "How electric motors work"? Or are you asking how to arrange the motor, belt and cylinder?

    The very basic concept of spinning a wheel. I've been thinking about it, and believe that because spinning a magnet in a coil of copper wire creates an electric charge, that a magnet in a charged coil of copper wire should spin. Confirmation?

    Yes, that is correct. You have just invented the electric motor. Congratulations!

    Unfortunately, you are about 200 years too late. But it is smart to have figured this out for yourself.

    Note that you need to use alternating current in the coil (known as "commutation") otherwise you will have static field and the magnet will just stay in the same place.

    Yay!
    Now for commutation, how could i achieve this? Some kind of capacitor system bouncing a current between the two edges of the cylinder? Or just a switch connecting the original battery to the system to be shut off once the charge enters the coil? But that might produce too much heat...

    This might give you some ideas: Electric motors and generators

    (Note: I was wrong, there are DC motors, although they still end up reversing the current in the coil mechanically)

    This article is giving me a headache, but from what it tells me, an induction motor is my best bet. Back to understanding it then.
