A bar magnet is 10cm long.Its magnetic moment is 0.4 Am^2.It is placed in magnetic meridian with its north pole towards north. If the neutral point is obtained at distance if 10cm from the center of the magnet find the horizontal component if earth’s magnetic field.

How many neutral points on a horizontal board are there and why when a magnet is held vertically on the board?
