Is magnetic force weaker than electric force?

Magnetic forces are much stronger than electric forces when you compare them at the saturation and breakdown strengths of materials. That is the reason why all practical electromechanical conversion devices use magnetic forces. Is magnetic field stronger than electric? The way in which charges and currents interact with the electromagnetic field is described by Maxwell’s …
