What are magnetic field lines. List two important properties of magnetic field lines.
What are magnetic field lines. List two important properties of magnetic field lines.
Solution
The lines representing magnetic field around a magnet.
[Diagram of a bar magnet (S-N) with curved field lines emerging from N pole and merging into S pole]
Properties:
No two field lines cross each other.
Field lines emerge from north pole and merge at south pole.
Field lines are closed curves.
The direction of the field lines inside the magnet is from its south pole to north pole.
