Explain why two magnetic field lines never intersect each other.
Answer: Two magnetic field lines never intersect each other because if they did, it would mean that at the point of intersection, the compass needle would point in two different directions at the same time, which is physically impossible.
Solution
A magnetic field line represents the direction of the net magnetic field at any point. A single point cannot have two distinct directions for the magnetic field vector.
