Representation of the magnetic field. Path along which an imaginary free north pole would tend to move. The tangent at any point on the magnetic field line gives the direction of the magnetic field at that point.
Characteristics of magnetic field lines :
(a) Emerge at north pole and merge at south pole. Inside the magnet, the direction of field lines is from south pole of magnet to its north pole, are closed curves.
(b) At the points where the magnetic field is stronger, field lines are crowded and vice-versa.
(c) No two magnetic field lines can intersect each other.
