A very long, straight solenoid with a cross-sectional area of 2.00 cm2 is wound with 94.1 turns of wire per centimeter. Starting at t = 0, the current in the solenoid is increasing according to i(t)= ( 0.170 A/s2 )t2. A secondary winding of 5.0 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 3.2A ?
