Question

write any 4 properties of magnetic field lines ani explain why two magnetic field lines cannor intersect with each other​

Answer 1

Answer:

1 - magnetic field does not intersect each other because if they intersect ......then on the intersection point there is two tangent drawn and the tangent gives the direction of electric field .....and at a point the two tangent can not be possible ............so the magnetic field can't intersect each other......

Answer 2

Answer:

1.they don't interset each other

2.magnetic field always starts from north pole to South pole.

3.it is vector quantity.

4.they always form closed loops

Explanation:

if magnetic field lines interset each other,then at the intersection point there will be two directions of the same field which is not possible .hence the field lines do not cross or interset each other
