Question

1. (a) Why do not two magnetic lines of force intersect each other?​

Answer 1

Two magnetic lines of force can never intersect each other because if they do so , at the point of intersection two tangents can be drawn and the compass needle would give two directions of magnetic field at the same point .

Since , magnetic field is a vector quantity , having different directions at a same point is not possible . Hence , two magnetic lines of force never intersect each other .

Some other information :

1. Two electric lines of force too never intersect each other .
2. Magnetic field lines are continuous and closed curves .
3. Magnetic field lines density is more near the poles where its strength is more .
4. They emerge from the north pole and terminate at south pole .

Answer 2

Answer:

hey mate here is your answer...

Explanation:

➡️ If the two magnetic lines of force intersect each other it would mean that there are two directions of the magnetic field at the point of intersection, which is not possible.
