A 8.00 cm diameter wire coil is iniA 6.70cm diameter wire coil is initially oriented so that its plane is perpendicular to a magnetic field of 0.570T pointing up. During the course of 0.180s, the field is changed to one of 0.300T pointing down. What is the average induced emf in the coiltially oriented so that its plane is perpendicular to a magnetic field of 0.510 T pointing up. During the course of 0.180 s, the field is changed to one of 0.250 T pointing down. What is the average induced emf in the coil?
