Question

How can the magnitude of induced current in a coil be increased?

Answer 1

1. Relative motion of magnet in and out of the coil
2. Number of turns of coil must be increased..
3. Strength of a magnet must be increased..

Answer 2

The magnitude of the induced current depends on the rate of change of magnetic flux or the rate of cutting of the magnetic field lines.

The factors that affect the magnitude of the induced current are,

1. The number of turns of the coil

=> As the number of turns increases, the magnitude of the induced current increases.

2. The speed of the relative motion of the conductor and the magnetic field

=> As the speed of the relative motion of the magnet increases the magnitude of the induced current increases.

3. the strength of the magnet

=> Increasing the strength of the magnet, will increase the magnitude of the induced current
