A 100-turn circular loop of wire that has a radius of 2.5 cm lies in the plane perpendicular to a spatially uniform magnetic field. During a 0.12-s time interval, the magnitude of the field increases uniformly from 0.2 T to 1.5 T. Determine the magnitude of the emf induced in the loop during the time interval.
