Unipoplar Induction and Weber's Electrodynamics
Keywords: unipolar induction, electrodynamics, conductor, magnet, relative rotary motion
Unipolar induction is the generation of current on a conductor for the case in which the conductor and the magnet are in relative rotary motion. A typical case of unipolar induction is shown in figure 1. Since Faraday's experiments of 1932 on electromagnetic induction on rotation systems there are intense debates concerning the location of the seat of the electromotive force (emf)2.
