PHYS102: Magnetic Fields and Magnetic Field Lines
Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole. The last property is related to the fact that the north and south poles cannot be separated. It is a distinct difference from electric field lines, which begin and end on the positive and negative charges.

Magnetic field lines have several hard-and-fast rules: The direction of the magnetic field is tangent to the field line at any point in space. A small compass will point in the direction of the field line. The strength of the field is proportional to the closeness of the lines. It is exactly proportional to the number of lines per unit area ...
