The mutual inductance `M_12` of coil 1 with respect to coil 2.

The mutual inductance between two coils depends on

A pair of adjacent coils has a mutual inductance of 1.5 H. If the current in one coil changes from 0 to 20 A in 0.5 s, what is the change of flux linkage with the other coil?

Calculate the mutual inductance between two coils, when a current of 4.0 A changes to 8.0 A in 0.5 s and induces an e.m.f. of 50 mV in the secondary coil.

Show that coefficient of mutual induction for one coil due to current in the other coil always remains the same.

Show that coefficient of mutual induction for one coil due to current in the other coil always remains the same.

Two coils are placed closed to each other. The mutual inductance of the pair of coils depends upon
