A very small circular loop of radius a is initially (at t = 0) 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 `omega` about the common diameter. The emf induced in the smaller loop as a function of time t is

A

`(pia^(2)mu_(0)I)/(2b)omega cos(omega t)`

B

`(pia^(2)mu_(0)I)/(2b)omega sin(omega^(2) t^(2))`

C

`(pia^(2)mu_(0)I)/(2b)omega sin(omega t)`

D

`(pia^(2)mu_(0)I)/(2b)omega sin^(2)(omega t)`
