Question

I CAN'T ASK TEACHER. PLEASE KINDLY ANSWER WELL HERE ATLEAST. WHY DON'T TWO MAGNETIC FIELD LINES INTERSECT  EACH OTHER?

Answer 1

➖In simple words :-

⭕️If two field lines of a magnet intersect, then at the point of intersection, the compass needle points in two different directions which is not at all possible.

Hence, two field lines do not intersect each other.


➖Other way is that :-

Mathematically,

⭕️The two magnetic field lines can never intersect each other because two tangents can be drawn from that point of intersection which will give two directions of the field from the same point, which is impossible.

⭕️if they will intersect then will get two direction of magnetic field this can't be possible .

Answer 2

Two magnetic field lines do not intersect each other because if they intersect then there two tangents can be drawn at a single point only which is not possible , or in simple words we can say that at that point the compass needle will point in two different direction which is not possible.
