The rate of change of magnetic flux linked with the coil is equal to the magnitude of induced e.m.f.' this is the statement of

The magnetic flux linked with a coil is phi and the emf induced in it is e .

The magnetic flux linked with a coil is phi and the emf induced in it is e .

The magnetic flux in a coil is phi = 4t^2 + 4t + 4 . What is the magnitude of induced e.m.f. at t = 3sec?

The magnetic flux linked with the coil varies with time as phi = 3 t^2 + 4t + 9 . The magnitude of induced emf at t = 2 second is

The magnetic flux linked with a coil varies as phi=3t^(2)+4t+9. Find the magnitude of the emf induced at t = 2S.

Whenever the magnet flux linked with a coil changes, then is an induced emf in the circuit. This emf lasts
