A circular coil (620 turns, radius = 0.087 m) is rotating in a uniform magnetic field. At t=0s, the normal to the coil is perpendicular to the magnetic field. At t = 0.023 s, the normal makes an angle of 45° with the field because the coil has made one-eighth of a revolution. An average emf of magnitude 0.083 V is induced in the coil. Find the magnitude of the magnetic field at the location of the coil.
