World's Most Powerful Magnet Under Construction [Update]

Multiply the magnetic field strength of a refrigerator magnet by 2 million and you'll be in the ballpark of the strength of the magnet that researchers at the National High Magnetic Field Laboratory, based near Florida State University in Tallahassee, are trying to create. When completed later this year, the pulsed electromagnet, located at the lab's facility at the Los Alamos National Laboratory, in New Mexico, will reach 100 Tesla, the holy grail of magnetic field strength. And in another first, if all goes according to plan it will reach that level-about 67 times as high as a typical MRI-without blowing itself to smithereens.
