MHT CET Physics question

The coil of a suspended coil galvanometer has a very high resistance, when a momentary current is passed through the coil, it

(A)Shows steady deflection
(B)Gets deflected and comes to rest slowly
(C)Oscillates with the decreasing amplitudeCorrect
(D)Oscillates with the same amplitude

Answer: (C)

Solution

With a very high-resistance circuit the induced (eddy) current, and hence the electromagnetic damping, is small, so after a momentary current the coil is under-damped and oscillates with
