A magnetic field lines is defined as vector field which is a collection of many vectors drawn on a grid.

Explanation:

(a) The magnetic field lines have length dependent on the strength of the magnetic force.  Compass does not indicate the strength of a magnetic field.  If we draw a magnetic field line outside a bar magnet, the lines does not cross each other.

(b)The north pole of a freely suspended magnet gets attracted by magnetic south polarity of the earth and vice versa. Hence is always point north-south direction.
