A 119 turn circular coil of radius 2.09 centimeter is immersed in a uniform magnetic field that is perpendicular to the plane of the coil. During 0.157 second the magnetic field strength increases from 58.5 mT to 95.1 mT. Obtain the magnitude of the average EMF, in millivolts, that is induced in the coil during this time interval.
