A rectangular loop is made up of 50 turns of wire and has dimensions of 23 x 64 cm. It is located in a uniform 1 T magnetic field. Over a time of 1.2 s, the coil is rotated from a position where the plane of the coil makes an angle of 21o with the magnetic field to a position where the plane of the coil makes an angle of 74o. Calculate the average emf induced in the coil.
