ABCD, a wire frame of negligible resistance, is placed in uniform magnetic field (B) acting perpendicular to the plane of wire frame. It is rotated about point O in the same plane. The direction of angular velocity w is perpendicular and into the plane. If a resistance R is connected between A and D. Then find the current flowing through resistance. Answer: (3Bwl 2 )/(2R)
