A solenoidal coil with 30 turns of wire is wound tightly around another coil with 350 turns, The inner solenoid is 20.0 cm long and has a diameter of 2.10 cm. At a certain time, the current in the inner solenoid is 0.100 A and is increasing at a rate of 1500 A/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.
