Quizplus · Accepted Answer

The maximum emf (ε) generated in a spinning loop is given by ε = NABω, where N is the number of turns, A is the area of the loop, B is the magnetic field, and ω is the angular velocity in radians per second. Here, N = 10, A = π(0.03 m)^2, B = 0.50 T, and ω = 2π(60) rad/s. Calculating this gives ε ≈ 5.3 V.
