A very small circular loop of radius a is initially (at 
) coplanar and concentric with a much larger fixed circular loop of radius b. A constant current I flows in the larger loop. The smaller loop is rotated with a constant angular speed ω about the common diameter. The emf induced in the smaller loop as a function of time t is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
