Question
A current is induced in coil C1 due to the motion of current carrying coil C2.
(a) Write any two ways by which a large deflection can be obtained in the galvanometer G.
(b) Suggest an alternative device to demonstrate the induced current in place of galvanometer.
Solution
a) Two ways by which we can obtain deflection in the galvanometer is by:
i) Moving coil C2 towards C1 with high speed.
ii) By placing a soft iron laminated core at the centre of coil C1.
b) By replacing galvanometer with the torch bulb in coil C1, one can demonstrate the induced current. The bulb begins to glow as a result of the induced current.
