A circular coil (980 turns, radius = 0.043 m) is rotating in auniform magnetic field. At t = 0 s, the normal to the coilis perpendicular to the magnetic field. At t = 0.013 s,the normal makes an angle of 45o with the field becausethe coil has made one-eighth of a revolution. An average emf ofmagnitude 0.077 V is induced in the coil. Find the magnitude of the magnetic field at the location of the coil.
