Physics
A solenoidal coil with 20 turns of wire is wound tightly aroundanother coil with 320 turns. The inner solenoid is 21.0 cm long andhas a diameter of 2.50 cm . At a certain time, the current in theinner solenoid is 0.140 A and is increasing at a rate of 1800 A/s.
For this time, calculate the mutual inductance of the twosolenoids;
For this time, calculate the emf induced in the outer solenoidby the changing current in the inner solenoid.
