A small magnet of magnetic moment `pixx10^(-3) Am^(2)` is placed on the Y-axis at a distance of 0.1 from the origin with its axis parallel to the X-axix. 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.

Answer

[`2.6 xx 10^(-10) A`, clockwise direction when viewed from O]
