प्रश्न
Why don’t two magnetic lines of force intersect each other?
Two magnetic field lines do not intersect each other. Why?
उत्तर
- The two magnetic field lines do not intersect each other because if they do, it means that at the point of intersection, the compass needle is showing two different directions, which is not possible.
- Magnetic field lines cannot collide because opposing magnetic field directions are physically impossible at the same spot.
- Magnetic field lines indicate the direction of magnetic force experienced by a theoretical north pole at a certain location.
- Intersecting two field lines would result in opposing magnetic force directions, which contradicts the concept of a well-defined magnetic field.
- Magnetic field lines do not connect, which is consistent with the nature of magnetic interactions.
