Magnetic lines of force never intersect each other. The tangent to a magnetic line of force at any given point is the direction where a charge placed at that point will move to. If magnetic lines of force intersect, a charge placed at the intersection point will have to move in two different directions. It is therefore not possible for magnetic lines of force to intersect.
