In a 231-turn automobile alternator, the magnetic flux in each turn is fB = (2.36E-4 T*m2) cos(?t), where ? is the angular speed of the alternator. The alternator is geared to rotate three times for each engine revolution. When the engine is running at an angular speed of 1150 rev/min determine the maximum emf in the alternator.
