A neutral point is found on the axis of a bar magnet at a distance of `10cm` from one end. If the length of the magnet is `10cm` and `H=0*3gauss`, find the magnetic moment of the magnet.

A neutral point is found on the axis of a bar magnet at a distance of 10cm from its one end. If the length of the magnet be 10cm , and H=0*3G . Find the magnetic moment of the magnet.

A neutral point is found on the prolongation of the axis of a bar magnet at a distance of 10 cm from the nearer pole. If the length of the bar be 10 cm and H = 28 Am^(-1) , find the pole strength of the magnet.

A short bar magnet is placed in the magnetic meridian with its north pole pointing towards geographical south. A neutral point is found at a distance of 30 cm from the centre of the magnet. If the horizontal component of earth's field is 0.4G , calculate the magnetic moment of the magnet .

The intensities of magnetic field at two points on the axis of a bar magnet at distances of 10 cm and 20 cm from the middle point are in the ratio 18:1. Find the distance between the poles of the magnet.
