Question

A solenoid has a radius Rs 15.0 cm, length L 3.50 m, and Ns 6500 turns. The current in the solenoid decreases at the rate of 69.0 A/s. A circular coil with a single turn and radius rc 22.0 cm encircles the solenoid with its plane perpendicular to the axis of the solenoid. Determine the magnitude of the average induced electric field in the coil. 1.77E-2X How is the emf over a closed path related to the electric field around this path? How is the emf related to the time rate of change of flux? What is the area over which the magnetic flux changes in this case? What is the radius of the closed path in this case? V/m
