In a model AC generator, a 499 turn rectangular coil 11.0 cm by 30 cm rotates at 116 rev/min in a uniform magnetic field of 0.65 T.
(a) What is the maximum emf induced in the coil? 130 Correct: Your answer is correct. V
b) What is the instantaneous value of the emf in the coil at t = (π/30) s? Assume that the emf is zero at t = 0.
30.59 Incorrect: Your answer is incorrect. Your response differs from the correct answer by more than 10%. Double check your calculations. V
(c) What is the smallest value of t for which the emf will have its maximum value? .129 Correct: Your answer is correct. s
