Question

why don't two magnetic lines of force interact with each other.​

Answer 1

Explanation:

The magnetic field lines never intersect each other because if two or more lines intersect each other than it means that at that point of intersection, the magnetic field has two directions at the same point. This is not possible for a magnetic field to point in more than one direction at the same point

Answer 2

Answer:

Tangent at a point to the magnetic field line gives the direction of the net magnetic field at that point. If the magnetic field lines intersect, there will be be two directions of net magnetic field which is not possible. So, magnetic field lines do not intersect each other.
