A constant magnetic field of 1 T is applied in the x > 0 regions. A metallic circular ring of radius 1m is moving with a constant velocity of 1 m/s along the x-axis. At t = 0s, the centre of O of the ring is at x = -1m.

A constant magnetic field of 1 T is applied in the x > 0 regions. A metallic circular ring of radius 1m is moving with a constant velocity of 1 m/s along the x-axis. At t = 0s, the centre of O of the ring is at x = -1m. What will be the value of the induced emf in the ring at t = 1s? (Assume the velocity of the ring does not change.)
(1) 1 V
(2) 2πV
(3) 2 V
(4) 0 V

Correct answer: (3) 2 V
Explanation:
emf = BLV
= 1.(2R).1
= 2 V
