If the rate of change of current `2As^-1` induces an e.m.f. of 40mV in a solenoid, what is the self inductance of this solenoid?

If a rate of change of current of 4 A s^-1 induces an e.m.f. of 20 mV in a solenoid, what is the self-inductance of the solenoid?

Derive expression for self inductance for a solenoid.

In a coil of self-induction 5 H, the rate of change of current is 2 A s^-1 . Then, e.m.f. induced in the coil is

An e.m.f. of 250 muV is induced in a coil, when current in it changes from 10 A to 6 A in 0.4 s. What is the self inductance of the coil?

A long solenoid has 500 turns. When a current of 2 A is passed through it, the resulting magnetic flux linked with each turn of the solenoid is 4 xx 10^(-3)Wb. The self-inductance of the solenoid is

When the current changes fro +2A to -2A in 0.05 s, an e.m.f. of 8 V is induced in the coil. The coefficient of self-indution of the coil is

When the current in a coil changes from 2 A to 4 A in 0.05 s, an e.m.f. of 8 V is induced in the coil. The coefficient of self-induction of the coil is

Whenever changing current is passed through a conductor, an e.m.f. is induced, that is.
