Current Attempt in Progress A circular coil (720 turns, radius = 0.084 m) is rotating in a uniform magnetic field. At t=0 s, the normal to the coil is perpendicular to the magnetic field. At t = 0.021 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 0.048 V is induced in the coil. Find the magnitude of the magnetic field at the location of the coil. Number Units
