Question

Magnetic field lines never intersect each other because

• A. There will be two directions of the field at the same point.
• B. Feild lines repel each other
• C. Field lines follow discrete paths only
• D. If field lines intersect they create a new magnetic field within the existing field

Answer 1

The correct option is

A

There will be two directions of the field at the same point.

1. Two magnetic field lines can never intersect each other because if they do there will be two directions of the field at the same point, which is impossible.
2. The density of the magnetic field lines at any place gives information about the strength of the magnetic field at that place.
