A plane of 100 turns and a diameter of 10.0 cm is placed in a uniform magnetic field of density 6.0 x 105 T. The coil is rotated at 20 rev/s about a diameter perpendicular to the magnetic field. Determine the maximum instantaneous value of induced e.m.f. i. ii. (2 marks) Sketch a graph to show the induced e.m.f varies with time. Mark a point P on your graph for the coil in position parallel to the magnetic field line and Q for the perpendicular. (3 marks)
