An electric generator contains a coil of 100 turns of wire, each turn forming a rectangular loop 50cm
by 30cm. The coil is placed entirely in a uniform magnetic field with magnitude, B = 3.5T and
direction initially perpendicular to the coil's plane. What is the maximum value of the emf produced
when the coil is spun at 1000 rev/min about an axis perpendicular to the direction of the magnetic field.
