Pulsed Field Facility

Researcher using the 100 Tesla Pulse Field Magnet

The highest magnetic fields in the world - up to 100 T - are reached for a fraction of a second.

The National High Magnetic Field Laboratory's Pulsed Field Facility at Los Alamos National Laboratory operates an international user program for research in high magnetic fields. Our pulsed magnets and experimental capabilities are unique in the world and our ability to produce cutting edge science is a major attraction for LANL visitors.

After two decades of innovation, the Pulsed Field Facility has developed and maintained a set of numerous powerful pulsed magnets ranging from 50T to 100T, and up to the 300T Single Turn Magnet, of different pulse widths to support a wide variety of users.
