This implies that the magnetic flux through the surface of a closed volume always adds up to zero. There have been a few claims to the contrary, but no one ever came up with a solid reproducible demonstration. The corollary is that when you cut a bar magnet into two pieces, you don't get a separate north and south pole, but instead two smaller magnets with their own north and south poles each. It was formalized as one of Maxwell's laws, which, although formulated before relativity, turned out to fit in perfectly. Jeroen Belleman
