Question

Assertion (A) : Magnetic field lines around a bar magnet never intersect each other.\ Reason (R) : Magnetic field produced by a bar magnet is a quantity that has both magnitude and direction.\

Professor PC Thomas Classes · Answer

(a) : Magnetic field lines gives the direction of magnetic field. If they intersect each other, then at intersection point, It shows two directions of magnetic field, which is not possible. Hence, they never intersect each other. Magnetic field produced by bar magnet is a vector quantity.
