Plenary talk — Development of high field magnet technology and applications

Development of science and technology requires high magnetic field strength and good field quality. The pursuit of extremely high magnetic fields is an eternal scientific goal for scientists and engineers. It is an exciting cutting-edge technology full of challenges and has been essential for many significant discoveries in science and technology. Combined with power-electronic devices and related software, a whole magnet system can be built up from various types of scientific instruments and other equipment, and can find widespread applications in scientific research and industry. Magnet technology is currently playing a more and more important role in scientific and technological progress. Ultra-high magnetic fields help to give us much deeper understanding of the world of matter and have special significance for research into the origins of life and disease prevention. In this paper, basic magnet principles, methods of generating magnetic fields, magnetic field applications, and numerical methods for the design of magnet structures are briefly introduced and reviewed.
