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

A coil of 5 turns is threaded by a changing magnetic flux changing at the rate 5 xx 10^-3 weber per second. Find the average emf induced.

The northpole of a bar magnet is thrust into a coil of 100 turns so that the flux linkage increases from 1 microweber to 5 microweber in 1 millisecond. Calculate the average emf induced across the end of the coil.

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 area 1000 turns and each of area 0.01 m^2 is in a magnetic field of 10^2 T. The magnetic field is at 90^@ to the plane of the coil. The coil is removed from the field in 0.1 second. Find the emf induced across the ends of the coil.
