8. A long solenoid of radius a with n turns per unit length is carrying a time-dependent current I(t) = 1, sin(wt), where I, and w are constants. The solenoid is surrounded by a wire of resistance R that has two circular loops of radius b with b > a (see figure). Find the magnitude and direction of current induced in the outer loops at time t = 0. (6) I b
