A coil of area `0.75 m^2` and 1000 turns is kept perpendicular to a magnetic field of `0.15 Wb//m^2`. Calculate the change in magnetic flux through the coil when it isrotated through an angle of `30^@`about a diameter.If the time taken for the rotation is0.5s.What is the average value of e.m.f.induced in the coil?
