Detailed explanation-1: -Magnetic lines of force always cross each other.
Detailed explanation-2: -If magnetic field lines intersect each other, then at the intersection point there will be two directions of the same field which is not possible. Hence the field lines do not cross or intersect each other.
Detailed explanation-3: -Each point on the field line gives the direction of magnetic field. Now if two magnetic field line intersect each other then at that point there will be two direction of magnetic field which is not possible.
Detailed explanation-4: -Magnetic lines of force never cross, but must always form individual loops. The mutual repulsion of each magnetic line accounts for this effect. This explains why like poles repel each other. If the lines cannot cross each other, then they must exert a force against each other.
