A rectangular planar loop with 10 turns, and whose dimensions are 5 cm by 7 cm is placed between the poles of a permanent magnet and turned by a small windmill at a rate of 150 revolutions per minute. The magnetic field between the poles is 0.75 T. Which of the following expressions represents the emf (in volts) as a function of time t in seconds produced by the generator?
