A very long, straight solenoid with a diameter of 3.00 cm is wound with 40 turns of wire per centimeter, and the windings carry a current of 0.245 A. A second coil having N turns and a larger diameter is slipped over the solenoid so that the two are coaxial. The current in the solenoid is Part A What average emf is induced in the second coil if it has a diameter of 3.5 cm and N = Express your answer in microvolts. ramped down to zero over a period of 0.70 s. ?
