A solenoid has a cross-sectional area of 5.8 x 10-4 m2, consists of 330 turns per meter, and carries a current of 0.41 A. A 19-turn coil is wrapped tightly around the circumference of the solenoid. The ends of the coil are connected to a 2.1- resistor. Suddenly, a switch is opened, and the current in the solenoid dies to zero in a time of 0.072 s. Find the average current induced in the coil.
