A coil of wire consists of 135 loops, each with an area of 1.5x102m. A magnetic field is perpendicular to the surface of each loop at all times, so that == 0. At time to=0 sec, the magnitude of the field at the location of the coil is Bo=0.95T. Two (2) seconds later the magnitude of the field at the coil has decreased to B=0.75T. What is the average emf induced in the coil during this time?
