Question
A very long, straight solenoid with a cross sectional area of 1.92 cm2 is wound with 92.1 turns of wire per centimeter. Starting at t=0, the current in the solenoid is increasing according to i(t) = (0.180 A/s2)t2. A secondary winding of 5 turns encircles the solenoid at its center, such that the secondary winding has the same cross sectional area as the solenoid.
What is the magnitude of the emf induced in the secondary winding at the instant that the current in the solenoid is 3.2 A ?
