Question

Any four characteristics of magnetic field line

Answer 1

Magnetic field lines , like electric field lines , are imaginary lines representing the magnetic force experienced by any magnetic object when brought under its field .

Properties of magnetic field lines:

1. Magnetic field lines never intersect each other . If they do so , there would be two tangents at the point of intersection , showing there are two directions of magnetic field at that point which is not possible .

2. Magnetic field lines are continuous and closed loops .

3. Magnetic field lines emerge from north pole and merge at south pole .

4. The density of magnetic field lines depends upon the distance from the poles of the magnet.
