Magnetic field lines of two magnets are shown in figures $A$ and $B$. Select the figure that represents the correct pattern of the field lines. Give reasons for your answer. Also,name the poles of the magnets facing each other.

(B) Figure $(B)$ represents the correct pattern of magnetic field lines.
Reason: Magnetic field lines never intersect each other. If they were to intersect,it would mean that at the point of intersection,the magnetic field has two different directions at the same time,which is physically impossible.
The poles of the magnets facing each other are North poles,as the field lines are shown emerging from the magnets.
