Inductive Reactance

The opposition that an inductor presents to alternating current, due to the inductor's ability to store energy as a magnetic field.

Inductor

A passive electronic component that stores energy in its magnetic field.

Inductance

The property of a conductor by which a change in current in the conductor induces an electromotive force in both the conductor itself and in any nearby conductors by mutual inductance.
