A rectangular loop is made up of 50 turns of wire and has dimensions of 45 x 55 cm. It is located in a uniform 2 T magnetic field. Over a time of 0.3 s, the coil is rotated from a position where the plane of the coil makes an angle of 12 degrees with the magnetic field to a position where the plane of the coil makes an angle of 71 degrees. Calculate the average emf induced in the coil.
