Question

why do two magnetic field lines not intersect each other?​

Answer 1

$\huge \rm \dag \underline \color{aqua}{Required \: Answer}$

The field lines never intersect each other because tangent drawn by any point on the line of force gives the direction of magnetic field at that point.

If however, the two magnetic lines of force cross each other, then two tangents can be drawn at the meeting point indicating two different directions of the magnetic field at the same point which is not possible.

Additional facts about

magnets.

1. Magnets tend to lost their magnetic properties when heated, or mishandled (dropped/hammered).

2. If magnets are not stored properly, their strength keeps on decreasing with time. Hence, there are special ways to store different types of magnets. For example, bar magnets are “kept in pairs” , with their unlike poles on the same side and separated by a piece of wood. At the ends, two pieces of soft iron and placed.

We call these pieces as magnetic keepers.
