The armature of a simple ac generator has 50 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 900 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?
