Centers of two similar coils P and Q having same number of turns are located at the coordinates (0.4,0) and (0,0.3) such that the plane of coils are perpendicular to X-and Y-axis respectively. The areas of cross section of coils P and Q are in the ration 4:3 Coil P has 16 A current in clockwise direction and coil Q has 93–√A current in anticlockwise direction as seen from the origin. A small compass needle is placed at the origin. Find the deflection in the needle, assuming the earth’s magnetic field negligible and the radii of the coils very small compared to their distances from the origin.

A small magnet of magnetic moment π×10^−3 A m^2 is placed on the Y-axis at a distance of 0.1 from the origin with its axis parallel to the X-axis. A coil have 169 turns and radius 0.05 m is placed on the X-axis at a distance of 0.12 m from the origin with the axis of the coil coinciding with the X-axis. Find the magnitude and direction of the current in the coil for a compass needle placed at the origin, to point in the north-south direction.
