British Dictionary definitions for mutual-inductance
a measure of the mutual induction between two magnetically linked circuits, given as the ratio of the induced electromotive force to the rate of change of current producing it. It is usually measured in henries M, L12Also called coefficient of mutual induction
(my'ch-əl) A measure of the relation between the change of current flow in one circuit to the electric potential generated in another by mutual induction. Like inductance, mutual inductance is measured in henries.
