A solenoidal coil with 29 turns of wire is wound tightly around another coil with 310 turns. The inner solenoid is 25.0 cm
long and has a diameter of 2.50 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
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.
