Long‐Pulse 60‐Tesla Magnet Starts Routine Operation at Los Alamos

For experiments in very high magnetic fields, there are DC electromagnets that have operated continuously at fields as high as about 35 tesla and the National High Magnetic Field Laboratory (NHMFL) expects to generate fields close to 45 T early next year. Some high‐field DC magnets are purely resistive, others are hybrids that also contain a superconducting magnet. For higher fields, pulsed technology has been employed. The highest magnetic fields for experiments are produced in self‐destructing magnets, in which the pulse lasts a few microseconds before the magnet destroys itself.
