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 (A), (C) and (D) only
- B (A), (B) and (C) only
- C (A), (B), (C) and (D)
- D (B), (C) and (D) only
Answer & Solution
Correct Answer
(A) (A), (C) and (D) only
Step-by-step Solution
Detailed explanation
Statement (A): A galvanometer deflection indicates current. True. Statement (B): Faster magnet movement implies a larger induced EMF/current (Faraday's Law). False. Statement (C): The induced pole opposes the magnet's motion (Lenz's Law). N-pole towards coil induces N-pole,…
