Question

A solenoidal coil with 20 turns of wire is wound tightly around another coil with 320 turns. The inner solenoid is 25.0cm long and has a diameter of 2.50cm . At a certain time, the current in the inner solenoid is 0.100A and is increasing at a rate of 1700A/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.
