Which one of the following correctly explains why two magnetic field lines never intersect each other?
(a) Intersecting field lines would create a magnetic monopole at the crossing point, which cannot exist.
(b) Two field lines cannot meet because the small hypothetical north poles on them repel each other.
(c) At any point the magnetic field has a unique direction, so two field lines cannot cross.
(d) If field lines crossed, magnetic flux would be counted twice at that point, violating Gauss’s law for magnetism.
