1Answer
Following are the characteristics of magnetic field line
-
They represent the magnetic field.
-
They are directed from north to South Pole outside a magnet and from south to North Pole inside a magnet.
-
The field lines are closed curves.
-
The strength of magnetic field in a region is determined by closeness of the field lines in that region.
-
The closer the field lines are, greater will be the field strength and vice–versa.
-
No two field lines ever cross each other as it would mean two different directions of field at point of intersection, which is not possible.
-
The parallel lines represent the uniform magnetic field whereas converging lines or diverging lines represents the non-uniform magnetic field.
