A small coil of radius 0.002 m is placed on the axis of a magnet of magnetic moment `10^(5)` `JT^(-1)` and length 0.1 m at a distance of 0.15 m from the centre of the magnet. The plane of the coil is perpendicular to the axis of the magnet. Find the force on the when a current of 2.0 A is passed through it.
