Why two magnetic lines of force do not intersect each other?

The intensity of the magnetic lines is constant throughout and proportional to their proximity.
Reason – The two magnetic field lines do not connect because if they did, the compass needle would display two different directions at the place of intersection, which is impossible.

At a certain location in Africa, a compass points $12^{\circ}$ west of the geographic north. The north tip of the magnetic needle of a dip circle placed in the plane of magnetic meridian points above the horizontal. The horizontal component of the earth’s field is measured to be $0.16 \mathrm{G} .$ Specify the direction and magnitude of the earth’s field at the location.At a certain location in Africa, a compass points $12^{\circ}$ west of the geographic north.
