When the north pole of a bar magnet points south where will the neutral point lies?
When two magnetic fields act against each other, there exist certain regions or points where they totally cancel each others effect. When certain magnetic materials are placed at such region or points, they do not feel any force and so they don’t have any particular orientation. Such points are called as neutral point. Hence, neutral point is defined as that point in the magnetic field where the field due to a magnet is completely neutralized by the horizontal component of the earth’s magnetic field. When the north pole of a bar magnet points south then the cancellation of magnetic forces can occur only at certain points along the equatorial line where the fields are in opposite directions but equal in magnitude. That means the neutral point lies on the equatorial line of the magnet where the fields are in opposite directions with each other and equal in magnitude.
