Asolenoidal coil with 22 turns of wire is wound tightly around another coil with 330 turns. the inner solenoid is 21.0 cm long and has a diameter of 2.30 cm . at a certain time, the current in the inner solenoid is 0.140 a and is increasing at a rate of 1800 a/s .
for this time, calculate;
a) the average magnetic flux through each turn of the innersolenoid;
b) the mutual inductance of the two solenoids;
c) the emf induced in the outer solenoid by the changing current inthe inner solenoid
for any you can offer! explanation would be wonderful!
