m A circular coil (950 turns, radius 5 0.060 m) is rotating in a uni- form magnetic field. At t 5 0 s, the normal to the coil is perpendicular to the magnetic field. At t 5 0.010 s, the normal makes an angle of f 5 45° with the field because the coil has made one-eighth of a revolution. An average emf of magnitude 0.065 V is induced in the coil. Find the magni- tude of the magnetic field at the location of the coil.
