If the flux linked with the solenoid changes from 0 to 1 weber in 2 sec. Find the induced emf in the solenoid.

A long solenoid with 15 turns per cm 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 Induced emf In the loop while the current is changing?

Inertia of the circuit is thecause of self inductance of a coil. An Induced emf of 4V Is generated when the current in the circuit changes from 3 A to 4A in one millisecond. What is the seif inductance of the coll.
