Question

why the two magnetic field lines never be intersecting

Answer 1

Explanation:

THE two magnetic field lines can never intersect each other because two tangents can be drawn from that point of intersection which will give two directions of the field from the same point,which is impossible.So, the two magnetic field lines can never intersect each other.

Answer 2

Answer:

if magnetic field intersected each other then we get resultant vector if some magnetic charge pole is placed then it has to has to move two defined directions simultaneously . practically it is not possible . therefore magnetic field never intersect
