In the schematic design of an electric generator, the magnetic flux alternates as the rotor turns; this produces an alternating emf by electromagnetic induction. Take these parameter values: number of turns in the coil = 99; diameter of the rotor = 0.55 m; length of the rotor = 1.1 m; magnetic field = 0.2 T; Rotation frequency = 60 Hz (i.e., 60 revolutions per second). (a) What is the maximum magnetic flux? (b) What is the maximum emf?
