From Jean de Climont:As a consequence of the Rowland effect in a rotating conductor, the motion of electrons can not be the cause of magnetic fields and the intrinsic magnetic field of electrons is not a dipole but have a rotational structure. As electron motion plays no part in magnetic field, there is no problem of relativity within electromagnetic phenomena.
Deutsch https://youtu.be/ziR30kAWm5ohttp://editionsassailly.com/report_rotation.htmThe Maxwell-Ampere equation is false. There is not any vector relationship between the magnetic field of the electrons in an electric field, so in translation, and the current vector J. There is only a formal coincidence. The magnetic field of the current is proportional to the average magnetic intrinsic magnetic field of electrons itself proportional to the electric field in the conductor.
