Many a times it is asked that when a north (or)south pole of a magnet is placed on a horizontal board, where could be the neutral point I.e. the point where horizontal component of the earth,s magnetic field is cancelled by the horizontal magnetic field component of the other magnetic source . The following two figures may help in getting the answer. The first fig shows how the magnetic field lines surround a magnet. This clearly hints that when this magnet is placed on a horizontal board with north pole on the board, the horizontal component of the filed lines looks like those , drawn in the fig 2.
