A very small circular loop of radius a is initially coplanar and concentric with a much larger circular loop of radius b (>>a). A constant current I is passed in the large loop which is kept fixed in space and the small loop is rotated with constant angular velocity about a diameter. The resistance of the small loop is R and its inductance is negligible. Find the induced emf in the large loop due to current induced in smaller loop as a function of time.
