generation of an electromotive force (EMF) in a circuit by changing the current in that circuit; usually measured in henries

The creation of an electromotive force in a circuit by its own magnetic field.

The production of a counter-electromotive force in a conductor when its own magnetic field collapses or expands with a change in current in the conductor. The phenomenon caused by the expanding and collapsing fields of an electron that encircle other electrons and retard the movement of the encircled electrons.
