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 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.

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.

A bar magnet is 10 cm long is kept with its north (N) pole pointing north. A neutral point is formed at a distance of 15 cm from each pole. Given the horizontal component of earth's field is 0.4 Gauss, the pole strength of the magnet is
