"MAGNETISM: Jumbo magnet in Florida exerts worldwide pull"
An enormous magnet, boasting a rock-steady field and a bore twice the size found elsewhere, is expected to draw the global scientific community to its Florida home. Opened last month in Tallahassee, the magnetic system offers a 105-millimeter bore and a record birth "weight," or magnetic field. Standing 16 feet tall and weighing more than 15 tons, the National High Magnetic Field Laboratory magnet is expected to live at least 10 years, and could survive for decades. On its inception date, July 21, the magnet produced a uniform field of 21.1 Tesla, which is expected to hold steady for years, a product of the resistanceless state of the superconducting electrons orbiting its bore. The magnet is now being readied for an international user community and, thanks to its superconducting coils, it will stay running for years to clean up a backlog of experiments waiting for such a device.
