A circular of radius 0.157 m has turns. It is placed such that its axis is in magnetic meridian. A dip needle is supported at the centre of the coil with its axis of rotation horizontal, and in the plane of the coil. The angle of dip is 30∘ when a current flows through the coil. The angle of dip becomes 60∘ on reversing the current. Find the current in the coil assuming that the magnetic field due to the coil is smaller than the horizontal component of earth’s magnetic field, H = 3×10^−5 T
