Problem 10: A 75 turn, 10.5 cm diameter coil of an AC generator rotates at an angular velocity of 6.5 rad/s in a 1.4 T field, starting with the plane of the coil parallel to the field at time t = 0. Part (a) What is the maximum emf, En, in volts? Eo = Part (b) At what time, to, in seconds, is the maximum emf first reached? to = Part (c) What is the next time, t1, in seconds, at which the absolute value of the emf is maximum? t =
