Question

What conclusion is drawn regarding the magnetic field at a point if a compass needle at that point rests in any direction? Give reason for your answer.

March 30, 2024

Answer

If a compass needle at a point rests in any direction then we can say that the magnitude of the magnetic field at that particular point is zero.

The reason for this is that the earth’s magnetic field at that point is neutralized by the magnetic field of some other magnetized material.
