The principle that a change of current in one circuit can induce electromotive force in a neighboring circuit, equal to the ratio of the electromotive force in a circuit to the corresponding change of current in a neighboring circuit.
Mutual inductance. (n.d.). In YourDictionary. Retrieved from https://www.yourdictionary.com/mutual-inductance
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.
