What is an inductor?

A passive electrical device that generates a magnetic field when current is passed through it. When the current is removed, it "induces" a brief current in the opposite direction of the original; thus, "induction" is caused by the opening and closing of a DC circuit or the continuous changing of directions in an AC circuit.
