Question
A circular coil of 500 turns encloses an area of 0.04 m2. A uniform magnetic field of induction 0.25 Wb/m2 is applied perpendicular to the plane of the coil. The coil is rotated by 90o in 0.1 second at a constant angular velocity about one of its diameters. A galvanometer of resistance 25Ω was connected in series with the the coil. total charge that will pass through the galvanometer is -
