MHT CET 2022 Physics question

Whenever a magnet is moved towards or away from a conducting coil, an e.m.f. is induced, the magnitude of which is independent of

(A)the speed with which the magnet is moved
(B)the resistance of the coilCorrect
(C)the strength of magnetic field
(D)the number of turns of the coil

Answer: (B)

Solution

By Faraday's law the induced emf is . It increases with the number of turns (D), with the strength of the magnetic field (C, larger flux change) and with the speed of
