Question

Explain in brief the three different ways to induce current in a coil.

Answer 1

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.

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

(i) Moving a magnet towards a coil sets up a current in the coil circuit,

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