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.

Calculate magnetic induction at a distance of 20 cm from a pole of strength 40 Am in air.

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.

The intensities of magnetic field at teo points on the axis of bar magnet at distance of 10 cm and 20 cm from the middle point in the ratio 18 : 1 . Find the distance between the pole of the magnets.

A bar magnet has a length of 8cm. The magnetic field at a point at a distnace 3cm from the centre in the broadside-on position is found to be 4 xx 10^(-6) T . Find the pole strength of the magnet.

A 30 cm long bar magnet is placed in the magnetic meridian with its north pole pointing south. The neutral point is obtained at a distance of 40 cm from the centre of the magnet. Pole strength of the magnet is (The horizontal component of earth’s magnetic field is 0.34 Gauss)
