... Magnetic field lines similarly describe the structure of magnetic fields in three dimensions.They are defined as follows. If at any point on such a line we place an ideal compass needle, free to turn in any direction (unlike the usual compass needle, which stays horizontal) then the needle will always point along the field line (drawing below). Field lines converge where the magnetic force is strong , and spread out where it is weak. ... Exploration" home page (index) Glossary . ...
