A circular wire coil with 28 turns and radius 3.92 cm is placed in a uniform magnetic field of strength 8.56 T, directed perpendicular to the plane of the wire loops. Over a period of 3.98 s, the magnetic field fades away to zero. What is the average induced emf (voltage) in the coil over this period of time? 0.291 V O 0.175 V O 0.364 V
