A single circular loop of wire is placed inside a long solenoid with its plane perpendicular to the axis of the solenoid. The area of the loop is A1 and that of the solenoid, which has n turns per unit length, is A2. A current I=I0cos?t flows in the solenoid turns.
What is the induced emf in the small loop?
