Why do magnetic field lines never intersect each other?
(a) Because magnetic field lines always form closed loops.
(b) Because the spacing between magnetic field lines represents field strength, so they cannot meet.
(c) Because at the point of intersection the field would have two directions at once, which is impossible.
(d) Because at the point where they cross the magnetic fields would cancel each other out.
