An electric generator contains a coil of 120 turns of wire, each forming a rectangular loop 60.0 cm by 36.7 cm. The coil is placed entirely in a uniform magnetic field by magnitude B= 4.78 T and initially perpendicular to the coil's plane. What is in volts the maximum value of the emf produced when the loop is spun at 1280 rev/min about an axis perpendicular to the magnetic field?
