A technician wearing a circular metal band on his wrist moves his hand (from a region where the magnetic field is zero) into a uniform magnetic field of magnitude 1.6 T in a time of 0.38 s. If the diameter of the band is 7.0 cm and the field is at an angle of 45 with the plane of the metal band while the hand is in the field, find the magnitude of the average emf induced in the band. ___mV
