Monopole, maybe.

Monopole, maybe

On Feb. 14, 1982, a magnetometer operated by Blas Cabrera at Stanford University recorded the passage of what seemed to be a magnetic monopole. In the years since, no purported second sighting has occured that stirred any acceptance or enthusiasm. Now there is a possible second event, this time at Imperial College of the University of London, England, reported in the January/February CERN COURIER.

Magnetic monopoles would be single north or south poles flying free. Theories that posit an exact and complete symmetry between electricity and magnetism predict their existence; electric monopoles are very common. Magnetic monopoles are also very important in recent theories of particle physics and cosmology.

The second possible sighting -- called the "South Kensington event" after the section of London where Imperial College is located -- occurred Aug. 11, 1985. Since then the experimenters have considered and rejected several explanations for it, but they are still not completely ready to call it a monopole. Searches in South Kensington, Stanford and other places continue.
