Question

A conducting loop of area 5 cm² is placed in a magnetic field which varies sinusoidally with time.

(a) The induced electromotive force (emf) is constant.
(b) The induced emf is sinusoidal.
(c) The induced emf is zero.
(d) The induced emf is linear.

Answer 1

The induced emf in a conducting loop placed in a sinusoidally varying magnetic field is sinusoidal.

Step-by-step explanation:

The induced electromotive force (emf) in a conducting loop placed in a magnetic field that varies sinusoidally with time is sinusoidal. According to Faraday’s law of electromagnetic induction, a changing magnetic field induces an emf in a circuit. In this case, the changing magnetic field will cause a sinusoidal variation in the induced emf.
