Discuss Faraday's experiment of two coils for the generation of electric current in a coil.

(N/A) In the figure,two coils $C_{1}$ and $C_{2}$ are shown. Coil $C_{1}$ is connected to a galvanometer $G$,and coil $C_{2}$ is connected to a battery.
The steady current in coil $C_{2}$ produces a steady magnetic field. As coil $C_{2}$ is moved towards coil $C_{1}$,the galvanometer shows a deflection. This indicates that an electric current is induced in coil $C_{1}$.
When $C_{2}$ is moved away,the galvanometer shows a deflection again,but this time in the opposite direction.
The deflection lasts as long as coil $C_{2}$ is in motion.
When coil $C_{2}$ is held fixed and $C_{1}$ is moved,the same effects are observed. Again,it is the relative motion between the coils that induces the electric current.
