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?

The magnitude of the induced emf in a coil of inductance 30 mH in which the current changes from 6A to 2A in 2s is

A varying current in a coil changes from 10A to zero in 0.5 s. If the the average emf induced in the coil 2V, the self inductance of the coil is

A varying current in a coil changes from 10A to zero in 0.5 s. If the the average emf induced in the coil 220V, the self inductance of the coil is

A tong solenoid with 15 turns per em has a small loop of area 2.0 cm^(2) placed inside the solenoid normal to its axis, If the current carried by the solenoid changes steadily from 2.0 A to 4.0 A in 0.1 s, what is the inducced emf in the loop while the current is changing?

Calculate the mutual inductance between two coils when a current of 2A changes to 6A in 2 seconds and induces an emf of 20 mV in the secondary coil.
