Would this wheel spin from magnetic force?

  1. Jun 27, 2011 #1
    Recently I was thinking random thoughts and thought to myself, if there was a windmill like wheel with powerful magnets on each blade, would it spin? Here is a poorly drawn picture to help explain myself:

    The N's and S's are representing the different poles. Excuse my poor paintdrawing skills... lol paint is difficult to be precise in :P

    Anyway, i'm pretty sure it wouldn't spin(it doesn't seem likely), but can any of you think of a structure that would spin? This sort of stuff interests me. Thanks :D

    Hi ShaneD, welcome to PF!

    You can certainly put magnets on a rotor and make it spin, that is what an electric motor does. Of course, you obviously also have to create a field outside of the rotor to push it. That assembly is called the stator.
