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 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 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 bar magnet of length 14 cm is placed in the magnetic meridian with its north pole pointing towards the geographic north pole. A neutral point is obtained at a distance of 18 cm from the center of the magnet. If B_(H)=0.4 G, the magnetic moment of the magnet is (1G = 10 ^(-4) T)
