A very small circular loop of radius a is initially coplanar & concentric with a much larger circular loop of radius b `(gtgta)`. A constant current is passed in the large loop which is kept fixed in space & the small loop is rotated with angular velocity omega about a diameter. The resistance of the small loop is R & its self inductance is negligible. The current in the larger loop is clockwise.   Find the current in the small loop as a function of time.
