Based on the field lines, what are the poles of the magnets?

The magnetic field direction is the same direction a compass needle points, which is tangent to the magnetic field line at any given point. The strength of the B-field is inversely proportional to the distance between field lines. It is exactly proportional to the number of lines per unit area perpendicular to the lines. A magnetic field line can never cross another field line. The magnetic field is unique at every point in space. Magnetic field lines are continuous and unbroken, forming closed loops. Magnetic field lines are defined to begin on the north pole of a magnet and terminate on the south pole.
