Question

Explain different ways to induce current in a coil.

Answer 1

Electric current can be induced in a coil due to the relative motion between the coil and a magnetic field.

There are two ways to do so.

1. Inducing current on a coil by moving the coil in a magnetic field
2. Inducing current on a coil by by changing the  magnetic field across it.
3. By taking two cunductiong coils and insert them over a non conducting cylindrical roll then on changing current flowing in one coil, an induced current is obtained in the other coil.

Answer 2

Answer:

The different ways to induce current in a coil are as follows:

(i) If a coil is moved rapidly between the two poles of a horse-shoe magnet, then an electric current is induced in the coil.

(ii) If a magnet is moved relative to a coil, then an electric current is induced in the coil.
