Figure shows a coil C connected to a galvanometer G. When the North-pole of a bar magnet is pushed towards the coil, the pointer in the galvanometer deflects. Regarding this set up, the following statements are given:

(A) It indicates the presence of electric current in the coil.
(B) The deflection is found to be smaller when the magnet is pushed towards the coil faster.
(C) There is repulsion in the moving magnet and the magnetic pole induced in the coil facing towards the N pole of the magnet.
(D) If the bar magnet does not move, there is no induced current in the coil.

Choose the correct answer from the options given below:

(A), (C) and (D) only

The correct answer is Option (1) → (A), (C) and (D) only

Explanation:

(A) ✔ True — The deflection of the galvanometer indicates that an induced current flows in the coil due to electromagnetic induction.

(B) ✖ False — The deflection becomes larger when the magnet is moved faster, because the rate of change of magnetic flux is greater.

(C) ✔ True — According to Lenz’s law, the induced current opposes the cause producing it; hence, the coil develops a pole that repels the approaching North pole of the magnet.

(D) ✔ True — If the magnet is stationary, there is no change in magnetic flux, so no induced current is produced.
