In a uniform magnetic field with intensity R, a flat coil of wire is located in such a way that its plane is perpendicular to the lines of force. The coil is connected to a galvanometer. The total charge flowing through the galvanometer when the coil is turned is equal to Q. At what angle was the coil turned? Perform a numerical calculation for the case of Q = 9.5 10-3 k, H = 105 a/m, coil area S = 103 cm2, coil resistance R = 2 ohms.
