    Hallo everyone its been a while,

    Wanted to know something about homopolar motors...

    When looking at this photo here:


    It seems difficult for me to imagine how back-EMF is generated...
    Since the conductor is not moving now is it?

    The only logical answer to me is: When the magnet is moving, its generating a C-EMF to that wire. But not all of it only the small part where its close to the magnet.
