A square coil of side 548-cm in an ac generator rotates at, Ask an Expert

Academics

A square coil of side 5.48-cm in an ac generator rotates at 50.0 Hz and develops an emf of 225V (rms).

(a) If the coil contains 805 turns, find the magnitude of the magnetic field in which it rotates.

(b) If the magnetic field were 0.186 T and the generator were to rotate at 60.0 Hz, what would be the rms emf developed by the generator?
