The Edge Effect in a Rectilinear Motional Induction Experiment

Abstract

Modification of a previously described rotational unipolar induction experiment leads to a rectilinear version of the same, in which the induction of an electromotive force can be obtained independently of the relative motion between magnet and conductor, even when both are moving in a straight line. This experiment seems to contradict the usual relativistic canon that motional electromagnetic induction always requires relative motion between conductors and magnets. The theoretical and practical consequences of the new experiment are discussed.
