A coil of insulated copper wire is connected to galvanometer. What would happen if a bar magnet is (i) pushed into the coil? (ii) withdrawn from inside the coil? (iii) held stationary inside the coil?
Text Solution
Verified by Experts
(a) Deflection in the galvanometer needle will be more when it is pushed into the coil. The motion of the magnet with respect to the coil procduces an induced potential difference which sets up an induced clectric eurrent in the coil. As a result, galvanometer gives a deflection towards the left. (b) Larger deflection in opposite direction as compared to the case (a) will be seen. When the direction of the motion of the magnet is measured then the direction of the movement of the current is also measured. This is the reason for the deflection of the needle in the opposite direction. (c) If the bar magnet is held stationary, then there is no induced current in the coil, because
there is no change in magnetic field through it. As a result, galvanometer does not show any deflection.
