A constant magnetic field of 1T is applied in the x > 0 region. A metallic circular ring of radius 1m is moving with a constant velocity of 1m/s along the x-axis. At t = 0 s, the center of O of the ring is at x = -1m.
What will be the value of the induced emf in the ring at t = 1 s? (Assume the velocity of the ring does not change.)
A
1V
B
C
2V
D
0V
Text Solution
Verified by ExpertsThe correct answer is:
C
Emf = BLV
= 1.(2R).1
= 2V
