The armature of a simple ac generator has 30 circular loops of wire, each with a radius of 10 cm. It is rotated with a frequency of 60 Hz in a uniform magnetic field of 500 mT.
Part A: What is the maximum emf induced in the loops?
Part B: How often is this value attained?
Part C: If the time period in part B were cut in half, what would be the new maximum emf value?
