New result in hunt for mysterious magnetic monopoles
(PHYSorg.com Physics)

Cutting a magnet in half yields two magnets, each with its own north and south pole. This apparent absence of an isolated magnetic pole, or `magnetic monopole,` has puzzled physicists for more than a century. It would seem perfectly natural for a magnetic monopole to exist; Maxwell`s equations would reflect complete symmetry between electricity and magnetism if particles with magnetic charge were observed. But the mystery remains: While every known particle is either electrically charged or neutral, none have been found to be magnetically charged.
