I am a high school student of Taiwan. I'm investigating the parameters that determine the angular velocity of the strong magnet(RbFeB magnet) of the homopolar motor now.
And what beset me is that I don't know how a current passes through a strong magnet.
I know that the surface of a RbFeB magnet is electroplated with a layer of conductive and metal material.
I wonder if the current passes "through" the magnet or passes along the surface of the magnet. (I don't know how to prove it.)
Thanks for your help!!!!!!!!!!!
