Question

Give reason two magnetic field lines do not intersect each other

Answer 1

Magnetic field lines can never intersect one another because if they intersect, then at the point of intersection, the magnetic field lines will be in two different directions (at the same point) which is not possible. Hence the magnetic field lines do not intersect each other.

Hope it helps

Answer 2

If two magnetic lines of force intersect with each other than there would have been two directions of magnetic field at the point of intersection, which is not possible.
