Question

Consider a magnetic dipole kept in the north to south direction. Let P₁, P₂, Q₁, Q₂ be four points at the same distance from the dipole towards north, south, east and west of the dipole respectively. The directions of the magnetic field due to the dipole are the same at

(a) P₁ and P₂
(b) Q₁ and Q₂
(c) P₁ and Q₁
(d) P₂ and Q₂

Answer 1

(a) P₁ and P₂
(b) Q₁ and Q₂



We know that magnetic field lines are directed from the north pole to the south pole. From the given figure, we can say that the direction of magnetic field $\underset{B}{\to }$ is the same only at points P₁ and P₂ and at points Q₁ and Q₂.
