Do magnets ever run out of charge

http://scienceline.ucsb.edu/getkey.php?key=507 WebMagnetic fields are relativistic electric fields (ie. the creation of an electric field due to space contraction from moving charges), but this was not known until Einstein's theory of relativity. Before relativity was discovered, magnetic fields were known to be generated by current (ie. moving charges) or changing electric fields. Comment
