Describe the magnet coil experiment to give the value of peak emf induced.

Describe the Urey and Miller's experiment.

What is peak value of AC.

State any two factors on which the maximum value of alternating e.m.f induced in the secondary coil of a transformer depends.

What is the basic cause of induced e.m.f.?

Describe Morgan's experiment.

The primary coil of a transformer has 100 turns and the secondary coil has 300 turns. If the peak value of the alternating emf applied to the primary coil 150v, what is the peakvalue of the alternating emf obtained across the secondary coil?

A straight conductor of length 0.4 m is moving with a velocity of 7m//s , in a magnetic field of induction 2 Wb//m^2 . The value of the maximum induced e.m.f. in the conductor is

The magnetic flux through a coil is 5 xx10^-4 Wb at time t = 0. It reduces to ten percent of its original value in 0.5s. The magnitude of e.m.f. induced in the coil is

The value of mutual inductance of two coils is B 10 mH. If the current in one of the coil changes from 5A to 1A in 0.2 s, calculate the value of emf induced in the other coil. Also calculate the value of induced charge passing through thecoil if its resistance is 5 ohm.
