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 magnet placed in the magnetic meridian with its north pole pointing north of the earth produces a neutral point at a distance of 0*15m from either pole. It is then broken into two equal parts and one such piece is placed in a similar position. Find the position of the neutral point.

A magnet placed in the magnetic merdian with its north pole pointing north of the earth produces a neutral point at a distance 0.15 m from either pole. It is then broken into two equal pieces and one such piece is placed in a similar position. Calculate the position of the neutral point. where will the neutral point be if the other piece is placed over the previous one with like poles together ?
