Q. No 13: A coil of insulated copper wire is connected to a galvanometer. What will happen if a bar magnet is (i) pushed into the coil, (ii) withdrawn from inside the coil, (iii) held stationary inside the coil?
Ans: (i) when magnet is pushed near a bar magnet then it induces current due to electromagnetic induction.
(ii) When the bar magnet is withdrawn from inside the coil of the insulated copper wire again the current is induced in the coil but this time it is in reverse direction.
(iii) When a bar magnet is held stationary inside the coil then no current is induced that’s why galvanometer will show no deflection.
