A short bar magnet is placed horizontally in N-S direction,with its north pole pointing to the north of earth.In this case,the neutral point is obtained

A short bar magnet is placed horizontally in N-S direction,with its N-pole pointing to south of earth.In this case,the null point on its axis is obtained if

A short bar magnet is placed in the magnetic meridian with its north pole pointing towards north of the Earth and a neutral point at a distance of 0.2 m is obtained from either pole. The magnet is now broken into two equal parts and one such part is placed in the similar position. Calculate the neutral point obtained in this case.

A short bar magnet is placed in magnetic meridian with its north pole pointing toward south: Its magnetic moment is 2Am^(2) . Neutral point is obtained 10cm from centre of magnet toward north. Calculate horizontal component of earth's magnetic field.

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 .

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)
