A new explanation to the magnetic force between two conductors due to their respective currents is proposed. It is based upon the strict usage of Coulomb’s original force law.
It is shown that this purely electrostatic law is capable of explaining also the magnetic force between currents. The reason is the inhomogeneous propagation of the electric field from different parts of continuously distributed moving charges, thereby causing a net difference between the field from the moving electrons and the immobile ions respectively in a conductor. Within the scope of this investigation it was also found that a D.C. voltage source must have inherited a direct current at the poles, opposite to the direction of the current through the circuit.
Using these concepts, experiments upon a set of Ampere’s Bridge, performed by Moyssides and Pappas [J. Appl. Phys. 59, 19 (1986)] can be satisfactorily explained.
