An electron in motion carries a magnetic field ... Quiz question:-- 1. Does its magnetic field travel fixed to the electron, and is therefor a -moving- magnetic field and induces an electrostatic potential in a perpendicular wire reaching-but-not-preventing the electron...? 2. If not, Does this prove the existence of an absolute aether (not necessarily constant or stable) in which the magnetic field exists as the consequence of a passing electron ... or conversely existing...? 3. Or, Does an electrostatic potential exist solely by the passing electron "pushing" its way passed...? Ray.
