| Neutral Points in a Magnetic Field |
|
| As a result of two magnetic fields acting at the same place, the resultant field has a special feature. At a particular point, if the compass needle does not point in any particular direction, then there is no net magnetic field at the point. Such a point is called Neutral point or the Null point. |
| |
| A neutral point is a point where the resultant magnetic field is zero. |
| |
| Figure (a) and (b) shown below illustrate the null points when the magnet is placed in two different positions. |

 When the N pole of the magnet points
South and the magnet in the magnetic meridian. |

When the N pole of the magnet points
North and the magnet in the magnetic meridian. |
| |
| At the two points marked X in figure, the earth's magnetic field and the magnet's field are exactly equal and opposite and the resultant field is zero. These points are called the neutral points. |
