We know that magnetic field is produced by a current carrying wire with time varying current? My doubt is that- do the electrons in motion cause the magnetic field or is it due to some another reason?

5Does this answer your question? How do moving charges produce magnetic fields? – Bhavay Aug 02 '20 at 11:50

1The magnetic force can be understood as a relativistic effect on the electric force. It results from Lorentz transformation of the electrostatic force for a stationary charged particle – Charles Francis Aug 02 '20 at 11:57

Is there current flowing through a permeant magnet? And could we apply ampere's law for finding field of permanent magnet? and Can magnetic force really be just electric force in a different frame? – HolgerFiedler Aug 02 '20 at 19:26
