An athelete peddles a stationary tricycle whose pedals are attached to a coil moving 100 turns each of area 0.1 m^2.The coil, lying in the XY plane, is rotated,in this plane, at the rate of 50rpm, about the Y axis, in a region where a uniform magnetic field, B = 0.01 T ( along +Z axis), is present. find the: a) maximum emf ;b) average emf generated in the coil over 1 complete revolution.
