Abstract

We describe two quasi trivial, old fashioned, but cleverly conceived, undisputable, experiments which disprove Kennard-type absolutistic interpretations of unipolar machines. Our findings are in agreement with Weber's statements concerning the role of relative motion in electrodynamics, as advanced by himself towards the middle of the 19th century. And also we agree with Mach's views concerning motion at the most general level. This work settles our earlier contributions devoted to unipolar induction. For nearly a century after its discovery by Faraday in 1832 the unipolar generator was a conundrum for the theory of electromagnetism D. F. Bartlett et al. Phys. Rev D 16 (12), 3459 (1977). We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances. - Isaac Newton
