Question

Consider the situation of the previous problem. The directions of the magnetic field due to the dipole are opposite at

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

Answer 1

(c) P₁ and Q₁
(d) P₂ 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 the magnetic field `vecB` is opposite at points P₁ and Q₁ and at points P₂ and Q₂.
