A 2-turn planer loop of flexible wire is placed inside a long solenoid of n turns per meter that canes a constant current Io The area A of tire loop is changed by pulling on its sides while ensuring that tire plane of the loop always remains perpendicular to tire axis of the solenoid. If n = 500 turns per meter, lo = 20A, and A = 20 cm² , what is the emf induced in the loop when dAldt = 100 ?
