mutual inductance

noun

, Electricity.

1. the ratio of the electromotive force in one of two circuits to the rate of change of current in the other circuit.

mutual inductance

noun

1. 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 ML12 Also calledcoefficient of mutual induction

mutual inductance

/ myo̅o̅′cho̅o̅-əl /

1. 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.

Word History and Origins

Origin of mutual inductance¹

First recorded in 1885–90

Example Sentences

Neumann founded a mathematical theory of induced currents, discovering a quantity M, called the “potential of one circuit on another,” or generally their “coefficient of mutual inductance.”

From Project Gutenberg

If the coils are neither parallel nor at right angles there will be some mutual inductance but not as much as if they were parallel.

From Project Gutenberg

As we pull the coil out the mutual effect becomes less and finally when it is well outside the mutual inductance is very small.

From Project Gutenberg

And this extra trouble would be because of the relations between gangs, that is, because of their “mutual inductance.”

From Project Gutenberg

There’s a case where their mutual relations, their mutual inductance, makes the job easier.
