    Undergrad Why does a homopolar generator work when the magnetic field rotates with the magnets?

    Yeah… I’m still confused about where your relative motion between the conductor and the magnetic field come from. Their both rotating together. The magnets and their fields are fixed (glued) to the disk, your just rotating the whole assembly. You have multiple magnetic fields rotating around an...

    Undergrad Why does a homopolar generator work when the magnetic field rotates with the magnets?

    So faradays paradox is often depicted as a circular copper disk on a shaft with a donut or toroidal magnet on one or either side of the disk. Spin the disk and magnets together voltage is produced. Since the magnets are rotating along their poles the orientation of the magnetic field compared...
