A coil of 15 turns and radius 10.0 cm surrounds a long solenoid of radius 2.20 cm and 1.00×103 turns/meter (see figure below). The current in the solenoid changes as I = 3.00 sin120 t, where I is in amperes and t is in seconds. Find the induced emf (in volts) in the 15-turn coil as a function of time. ε =
