In the figure SAQ 12(a) a bar magnet moving towards the right or left induces an e.m.f. in the coils (1) and (2). Find, giving reason, the direction of induced currents through resistors AB and CD. When the magnet is moving
towards the right.

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

A magnet is moved towards a coil. What is the source of electric current induced in the coil?

Current changes in time interval 5 s from 7 A to 2 A in a coil of self inductance 0.1 H. Find the value of induced e.m.f. and the direction of induced current in the coil.

The figure SAQ 14(a) shows two identical rectangular loops (1) and (2) placed along with a straight long current carrying conductor between them. What will be the direction of induced currents in the loops when they are pulled away from the condutor with the same velocity v?

The figures SAQ 13(a) shows a bar magnet M falling under gravity through an air cored coil. Plot a graph showing variation of induced e.m.f. with time(t). What does the area encloed by E-t curve depict?

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?

Current in a 10 millihenry coil increases uniformly for zero to oe ampere in 0.01 second. Find the direction and value of self-induced e.m.f.

The closed loop PQRS is moving into a uniform magnetic field acting at right angles to the plane of the paper as shown in Fig 6.50 state the direction in which the induced current flows in the loop.
