WebAmpere's Law states that for any closed loop path, the sum of the length elements times the magnetic field in the direction of the length element is equal to the permeability times the electric current enclosed in the loop. In the electric case, the relation of field to source is quantified in Gauss's Law which is a very powerful tool for ... WebWe need the current I passing through the area enclosed by the path. It’s equal to the current density J times the area enclosed. Since the current is uniform, the current …
