A 109 turn circulаr cоil оf rаdius 2.41 cm is immersed in а unifоrm magnetic field that is perpendicular to the plane of the coil. Over an interval of 0.159 s , the magnetic field strength increases from 58.3 mT to 98.3 mT . Find the magnitude of the average emf induced in the coil during this time interval, in millivolts.
