A solenoidal coil with 25 turns of wire is wound tightly
around another coil with 300 turns. The inner solenoid
is 25.0 cm long and has a diameter of 2.00 cm. At a certain
time, the current in the inner solenoid is 0.120 A and is increasing
at a rate of 1.75 * 10^3 A/s. For this time, calculate: the emf induced in the outer solenoid
by the changing current in the inner solenoid.
