Hybrid magnets are combined systems of highpower watercooled magnetsand superconducting magnets, having certain advantages in the production of steady high magnetic fields higher than 20 T. These fields are required for researches on high-field superconductors which may possibly be used for nuclear fusion reactors. In this paper the technology of the steady-state high-field magnet and the present status of world-wide high-field facilities are reviewed, followed bya brief description of our hybrid magnet project.
