Question

mutual inductance between two magnetically coupled coils depends on

Answer 1

rate of change of current in coil

Answer 2

The mutual inductance is a depends upon

• seperation

• number of turns

$\underline \bold{Mutual\: inductance}$

The phenomena of inducing current emf in an inductor as a result of growth or decay of current in nearly inductor is called as mutual induction.

If two inductors are coupled inductively then the flux linked in an inductor depends directly on the instant current in the the inductor.

¢ is directly proportional to I

¢ = M I

where M is called coefficient of mutual inductance.

The value of mutual inductance depend on the linkage of flux which is depending on the separation orientation of the two inductors.

The coefficient of mutual induction is numerically equal to the flux linked in the inductor caused by the unit current flowing in the nearby inductor.
