A very long, straight solenoid with a cross-sectional area of 2.40 cm² is wound with 86.5 turns of wire per centimeter. Starting at t = 0, the current in the solenoid is increasing according to i (t) = (0.168 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.
