A circular conducting loop of radius b = 10 cm is rotated about an axis along the diagonal of the loop with a constant rotational speed of 250 revolutions per minute inside a uniform magnetic field B = 3 T. If the loop has a resistance R = 15 ohms: (a) Calculate the emf of the loop as a function of time. (b) What is the magnitude of the induced current in the loop as a function of time? (c) If at to = 0 s the loop area was straight up in the plane of the paper, what is the magnitude and direction of the induced current att= 30s?
