Abstract
A possible electrical charge model based on the spinning time invariant point magnetic dipole within the framework of classical physics is outlined, as suggested by the admissible circular trajectory of a test charge around the magnetic dipole in its equatorial plane. The model depends on the moving force line hypothesis which has been claimed to have been disproved. The controversy about that issue at the turn of this century is reanalyzed. The mathematical model of the generalized homopolar generator is presented, which is fully in agreement with all experimental facts concerning the homopolar generator, except for a single result by Pegram which appears to be an error and which violates the Faraday law. It is shown that the moving force line hypothesis was apparently not disproved by Kennard as claimed. Thus the intriguing model of electrical charge is possible. Further experimental research with all kinds of spinning magnets appears to be justified and desirable in view of the potentially high significance of the research line initiated by Jehle with the quantum mechanical model of the charge in terms of spinning flux loop forms.
