Question

Why don't two magnetic lines of force belonging to the same field interseet
each other?

Draw magnetic field lines or magnetic lines of force around a bar magnet

Write the properties of magnetic lines of force.

Applying right hand thumb rule, find out the direction of the magnetic field
inside and outside a loop of wire carrying current in the clockwise direction
and lying on the plane of the table or the page.​

Answer 1

Answer:

The direction of magnetic field lines is always from the north pole to the south pole. If the field lines would cross each other then the direction of field line would change at the point of crossing which is practically impossible. Hence, two magnetic field lines never intersect each other.
