Avery long, straight solenoid with a cross-sectional area of 2.40 cm^2 is wound with 93.4 turns of wire per centimeter. starting at t = 0, the current in the solenoid is increasing according to i(t)= ( 0.169 a/s^2 )t^2. 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?
