Answer to Question #16236 in Electric Circuits for aaa

Question

A solenoidal coil with 22 turns of wire is wound tightly around another coil with 340 turns. The inner solenoid is 21.0cm long and has a diameter of 2.50cm . At a certain time, the current in the inner solenoid is 0.110A and is increasing at a rate of 1800A/s . a) For this time, calculate the average magnetic flux through each turn of the inner solenoid. b.) For this time, calculate the mutual inductance of the two solenoids; c) For this time, calculate the emf induced in the outer solenoid by the changing current in the inner solenoid.
