A magnetic dipole is aligned in the north-south direction. Suppose P₁ , P₂ , Q₁ , and Q₂ are four points placed at equal distances from the dipole towards the north, south, east, and west, respectively. The directions of the magnetic field due to the dipole are opposite at

Step-by-step solution

Let the magnetic dipole moment be m aligned along the North-South direction. Assume m points towards the North. Points P₁ (North) and P₂ (South) lie on the axial line of the dipole. The magnetic field at any axial point is in the same direction as the dipole moment. Thus, the magnetic fields at P₁ and P₂ are both directed towards the North. Points Q₁ (East) and Q₂ (West) lie on the equatorial line of the dipole. The magnetic field at any equatorial point is in the opposite direction to the dipole moment. Thus, the
