Question

what is neutral point of magnetic field

Answer 1

Neutral points or Null points are those points around a magnet, where the net magnetic field is zero.

Answer 2

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.
