8. A coil of radius r = 0.50 cm and 20 turns sits inside the center of a long, tightly wound solenoid of radius a = 1.0 cm, 5000 turns and length 10.0 cm. Looking down the axis of the solenoid, there is a clockwise current of strength 1.0 A and it is increasing at the rate of 0.50 A/s. The coil is oriented parallel to the individual loops of the solenoid (so that its cross section is also circular when looking own the solenoid axis). a. Find the magnitude of the induced emf in the coil and the direction of the induced current. b. Find the induced electric field outside of the solenoid, 1.5 cm away from the axis of the solenoid. (Ignore the coil inside the solenoid).
