A circular coil and a bar magnet placed nearby are made to move in the same direction. The coil covers a distance of `1m` in `0.5 sec` and the magnet a distance of `2 m` in `1 sec`. The induced emf produced in the coil

A coil and a bar magnet move with the same velocity. What will be induced e.m.f. in the coil?

If a magnet is held stationary and a coil is moved towards the magnet, will there be any induced e.m.f. produced in the coil?

The current in a coil decreases from 5 A to 0 in 0.1 sec. If the average e.m.f induced in the coil is 50 V, then the self inductance of the coil is

What is the change in magnetic flux produced in a coil in 25 s, if the induced e.m.f. In the coil is 2 mV ?

A varying current in a coil change from 10A to 0A in 0.5 sec . If the average emf induced in the coil is 220V , the self inductance of the coil is

A rectangular copper coil is placed in a uniform magnetic field of induction 40 mT with its plane perpendicular to the field. The area of the coil is shrinking at a constant rate of 0.5m^(2)s^(-1) . The emf induced in the coil is
