A circular wire coil with 26 turns and radius 3.81 cm is placed in a uniform magnetic field of strength 7.91 T, directed perpendicular to the plane of the wire loops. Over a period of 1.72 s, the magnetic field fades away to zero. What is the average induced emf (voltage) in the coil over this period of time?
