A 141 turn circular coil of radius 2.61 cm is immersed in a uniform magnetic field that is perpendicular to the plane of the coil. Over an interval of 0.177 s , the magnetic field strength increases from 53.1 mT to 96.9 mT . Find the magnitude of the average emf avg induced in the coil during this time interval, in millivolts.
av emf
E = N A (B2 - B1) / t
E = 141* 3.14* (0.0261^2) * ( 96.9 - 53.1)* 10^-3 / 0.177
E = 74.63 mV
