Mutual Inductance

Mutual Inductance is property of electric circuits in which an electromotive force so called emf is induced by the process of electromagnetic induction in one of the circuits by a change of current in any one of them. Or defining it in another way we can say mutual inductance of two nearby circuits is defined as the ratio of the emf induced in one circuit to the rate of change of current in the other electronics circuit. The term inductance coil or inductor is a device having the property of inductance. If we are given coil, the ratio of the electromotive force of induction to the rate of change of current in the coil is called the self-inductance of the coil. In more simpler terms Self-inductance is the number of flux linkages per unit current. Flux linkage is the product of the flux and the number of turns in the coil. Self-inductance does not affect a circuit in which the current is unchanging type but it is of great importance when there is a changing current, because of an induced emf during the time of change. The (SI) unit of mutual inductance is the Henry, the same as the unit of self-inductance.

Mutual Inductance

The fact that a change in the current of one coil affects the current and voltage in the second coil is quantified in the property called mutual inductance

Mutual Inductance

The constant M, called the mutual inductance of the two circuits, is dependent on the geometrical arrangement of both circuits

Mutual inductance and basic operation : TRANSFORMERS

This effect is called mutual inductance: the induction of a voltage in one coil in response to a change in current in the other coil
