In the second experiment, Faraday replaced ‘X’ with ‘Y’ for checking the deflection in the galvanometer. Identify X and Y.

(a) X ➔ Current carrying coil; Y ➔ Bar magnet

(b) X ➔ Bar magnet; Y ➔ Current carrying coil

(c) X ➔ Bar magnet; Y ➔ Battery

(d) X ➔ Current carrying coil; Y ➔ Battery

I have been asked this question during an internship interview.

I'd like to ask this question from Faraday and Henry Experiments in division Electromagnetic Induction of Physics – Class 12

Best answer
The correct choice is (b) X ➔ Bar magnet; Y ➔ Current carrying coil

Explanation: In the second experiment, Faraday replaced the bar magnet by a second current carrying coil that was connected to a battery. As we move the second coil towards the primary coil, the pointer in the galvanometer undergoes deflection, which indicates the presence of the electric current in the first coil.
