Why do two magnetic field lines never intersect each other?
(a) Because like magnetic poles always repel each other, the field lines keep away and never cross.
(b) Because magnetic field lines are closed loops that naturally avoid each other and hence cannot intersect.
(c) Because at a given point a magnetic field cannot have two different directions, so lines cannot cross.
(d) Because magnetic field lines trace the path of iron filings, and two filings cannot occupy the same place, so the lines never intersect.
