The National High Magnetic Field Laboratory has developed and operated large, high-field dc and pulsed magnets for research in condensed matter physics. We are now developing three resistive/superconducting hybrid magnets with fields ranging from 25 to 45 T, and are developing concepts for hybrid magnets up to 60 T as well human-head MRI magnets up to 20 T and repetitively pulsed magnets to reach 60 T every 30 sec.
