12. A 50 turn rectangular coil of 5.00 cm x 10.0 cm is allowed to fall from a position where B = 0 to a new position where B=0.500 T and the magnetic field is directed perpendicular to the plane of the coil. Calculate the magnitude of the average emf that is induced in the coil if displacement occurs in 0.250 s.
