Determine the maximum




A rectangular coil of size 5cm x 10cm has 200 turns and is supported on the axle which lies along one of the shorter sides. The axle of the coil is normal to a large uniform magnetic field in which the bax density is 0.5T and the coil is rotated about this axle at 1,500 r.p.m. Determine the maximum e.m.f. and the e.m.f. at an instant when the coil plane makes angle of 45o with the field direction.
