Question: A solenoidal coil with 25 turns of wire is wound tightly around another coil with 320 turns. The inner solenoid is 23.0cm long and has a diameter of 2.00cm . At a certain time, the current in the inner solenoid is 0.150A and is increasing at a rate of 1600A/s
Part A: For this time, calculate the average magnetic flux through each turn of the inner solenoid.
Part B: For this time, calculate the mutual inductance of the two solenoids;
Part C: For this time, calculate the emf induced in the outer solenoid by the changing current in the inner solenoid.
