Asolenoidal coil with 25 turns of wire is wound tightly aroundanother coil with 300 turns. the inner solenoid is 25.0 cm long andhas a diameter of 2.00 cm. at a certain time, the current in theinner solenoid is 0.120 a and is increasing at a rate of1.75x103a/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
