Two magnetic field lines produced by the same source never intersect.
Magnetic field lines represent the direction of the magnetic field at different points. If two magnetic field lines were to intersect at a point, it would mean that the magnetic field at that point has two different directions simultaneously, which is impossible.
Magnetic field lines are continuous curves forming closed loops (outside the magnet from North to South, inside from South to North). They are denser where the magnetic field is stronger. They originate from the North pole and terminate at the South pole outside the magnet.
