Inductance

See Also: Induction

Quantity that measures the electromagnetic Induction of an Electric Circuit component. The self-inductance L of a circuit component determines the magnitude of the Electromotive Force (EMF) induced in it as a result of a given rate of change of Current through the component. The mutual inductance M of two components, one in each of two separate but closely located circuits, determines the emf that each may induce in the other for a given current change. Inductance is expressed in units of henrys (see Henry, Joseph). A device designed to produce an inductance, e.g., a wire (see Conductor) coil, is called an inductor.
