mutual induction

[′myü·chə·wəl in′dək·shən]
The generation of a voltage in one circuit by a varying current in another.

Mutual Induction


a phenomenon in which magnetic coupling of two or more electric circuits is observed. Because of the coupling, an induced electromotive force is generated in one of the circuits if the current in the other circuit changes. Mutual inductance is a quantitative measure of magnetic coupling between circuits. The operation of transformers is based on mutual induction.
