inductance, quantity that measures the electromagnetic induction Electromagnetic induction is the production of an electromotive force (emf) in a conductor as a result of a changing magnetic field about the conductor and is the most important of the three phenomena. It was discovered in 1831 by Michael Faraday and independently by Joseph Henry.

The self-inductance, L, of a circuit component determines the magnitude of the electromagnetic force (emf) induced in it as a result of a given rate of change of the current through the component. Similarly, 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 henrys [for Joseph Henry Henry, Joseph, 1797–1878, American physicist, b. Albany, N.Y., educated at Albany Academy. He taught (1826–32) mathematics and natural philosophy at Albany Academy and was professor of natural philosophy (1832–46) at Princeton (then the College of

inductance

Property of a conductor, sometimes in the shape of a coil, that is measured by the size of the electromotive force (emf), or voltage, induced in it, compared with the rate of change of the electric current that produces the voltage. A steadily changing electric current produces a varying magnetic field, which induces an emf in a conductor that is present in the field. The magnitude of this voltage is proportional to the rate of change of the current. The inductance is the proportionality factor. The unit of inductance is the henry, named after Joseph Henry; one henry is equivalent to one volt divided by one ampere per second.

The magnetic field that is generated when a current is passed through an inductor, typically a wire coil. Inductance is measured in henrys (H). See inductor and induction.
