Abstract
A comprehensive revision of the Unipolar Inductor is presented. The study includes: # its historical origins, (Faraday, 1832 to 1854)
- the competing theories advanced to explain its operation (fixed line theory; moving line theory; Lorentz's force; Maxwell's (Faraday) flux law; vector potential theory; and Amperian electrodynamic theories (Ampere, Gauss, Weber)
- the thorny problem of seat of emf localization and its proposed experimental resolution by the author
- the vexing problem formulated by Feynman (that Maxwell-Faraday's flux law is not applicable to the inductor)
- a description of the major experimental tests of unipolar induction, including Kennard's 1917 experiment, the author's own modification of Faraday's inductor and some recent experiments (Marinov, Guala-Valverde, etc)
- the most relevant applications: in engineering (homopolar generators; brushless generators, and claimed over-100% efficient generators ); in astrophysics (origin of planetary and cosmic magnetic fields); and most importantly
- the theoretical relevance concerning the applicability or non-applicability of Special and General Relativity theories to the unipolar inductor, both in rotational and translational forms.
