Magnet at national lab generates largest magnetic pulse

Los Alamos National Laboratory

It might not look like much, but the electromagnet at the Pulsed Field Facility at Los Alamos National Laboratory set a record when it generated a 97.4-tesla field without destroying itself in the process. (High-powered magnets routinely rip themselves apart due to the large forces they create.) For comparison, the magnetic field of the Earth is about 0.0004 T, the field of a junkyard magnet measures 1 T, and magnets in MRI machines generate 3 T.

The Los Alamos magnet will let researchers from around the world explore the properties and quantum nature of materials.
