The current through a 1mH inductor changes from 5 ampere to 10 ampere in 1 millisecond. Find the emf induced.

The current in a coil of self inductance 1 mH changes from zero to 10 Ampere in a time interval of 10 millisecond. Find the emf induced across the coil and the energy stored during that time.

A coil of 200 turns is linked with a magnetic flux that changes from 10^-5 weber to 10^-4 weber is a millisecond. Find the emf induced across the coil.

The current flowig through an inductor drops from 10A to 2A in 2m sec. If the self inductance of the coil is 10mH, find the emf induced across the ends of the inductor.

Two adjacent coils have a mutual inductance of 200 mH. Find the emf induced in the secondary when the current through the primary is increased from 0 to 10 ampere in 10 millisecond.
