Two magnetic field lines do not cross each other because a magnetic field can have only one direction at a point. If two field lines crossed, it would mean the magnetic field has two directions at the same place, which is impossible.
Example: A compass needle always points in one direction at a particular point. If field lines crossed, the compass would not know which direction to point.
