  • Non-Local Motional Electrodynamics (2009) [Updated 7 years ago]

    We report some recent experiments on motional induction, performed on partially shielded circuits. Both electro and ponderomotive forces are unsensitive to magnetic shielding. Laplace and Lorentz local forces must be applied with considerable care when dealing with motional induction. 


  • The Homopolar Motor: A True Relativistic Engine (2002) [Updated 7 years ago]

    This article discusses experiments which enable the identification of the seat of mechanical forces in homopolar-machines reported earlier in this journal [J. Guala-Valverde and P. Mazzoni, Am. J. Phys. 63, 228-229 (1995); J. Guala-Valverde, P. Mazzoni, and K. Blas, ibid. 65, 147-148 (1997)]. We provide a suitable variation on a recent work "The Unipolar Dynamotor: A Genuine Relational Engine'' [J. Guala-Valverde and P. Mazzoni, Apeiron 8, 41-52 (2001)], where "relational'' implies "absolutely relativistic.'' Our view agrees with both Weber's recognition in the 19th century of the importance of relative motion in electromagnetic phenomena [A. K. T. Assis, Electrodynamics (Kluwer, Dordrecht, 1994)] and Einstein's 1905 statement concerning electromagnetism [Ann. Phys. 17, 891-921 (1905)].


  • The Unipolar Dynamotor: A Genuine Relational Engine (2001) [Updated 7 years ago]
    by Jorge A. Guala-Valverde, Pedro Mazzoni   read the paper:

    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


  • The Unipolar Faraday Generator Revisited (1993) [Updated 1 decade ago]

    When a charge moves, an electromagnetic field surrounding it appears. This field interacts with circuits, resulting in electromotive and ponderomotive phenomena. When a charge is at rest, the field reduces to the Coulomb field; the magnetic part of the Lorentz force F = qu X B is absent and neither pondero- nor electro-motive forces appear, no matter how magnets and circuits move. It is shown that neither absolute space nor STR are necessary to explain unipolar induction effect.
