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

A current through a coil of self inductance 10 mH increases from 0 to 1 A in 0.1 s. What is the induced emf in the coil?

The current in a coil changes from 0 to 20 A in 0.5S. If the induced emf is 80V, the self inductance of the coil is

A coil cosists of 400 turns of wire. Each turn is a square of side d= 20 cm. A uniform magnetic field directed perpendicular to the plane of the coil is turned on. If the field changes linearly from 0 to 0.50 T in 0.8 s, what is the magnitude of induced emf in the coil while is the field is changing?

The mutual inductance of a pair of coils is 0.75H. If the current in the primary coil changes from 0.5A to zero in 0.01s, find the average induced e.m.f. in the secondary.

A pair of adjacent coils has a mutual inductance of 1.5H. If the current in one coil changes from 0 to 10 A in 0.2s, what is is the change of flux linkage with the other coil?
