Question

one coil of resistance 40 ohm is connected to a galvanometer of 160 ohm resistance. The coil has radius 6 mm and turns 100. This coil is placed between the poles of a magnet such that magnetic field is perpendicular to coil. If coil is dragged out then the charge through the galvanometer is 32 microcoulomb. The magnetic field is:- (1) 6.55 T (2) 5.66 T (3) 0.655 T (4) 0.566 T
