Inductance is the influence of an electric field on a ferrous material, and the corresponding influence of that ferrous magnetic field back onto a conductor. Inductors can be used to step voltage up and down in the case of a transformer. In a DC circuit, inductors act similarly to a standard conductor, with only a small amount of wire resistance.
