Magnet Technology Beyond 50 T

The unique opportunities high magnetic fields offer scientific research, and their use as a tool for science, have motivated many activities to expand their technological limits. Because of the Lorentz forces, the successful design of high field magnets is a challenge at the frontiers of magnet technology, and it is equally a stimulus for the materials scientist. The quest for higher fields translates into the urgent need for ultra-strong materials with higher Young's modulus and conductivity. High field magnets are an ideal test bed for materials and concepts. Fields above 50 T can be generated with continuous and pulsed fields. We describe the technologies, which have been developed, the achievements and the potential for future improvements. We focus mainly on the field region between 50 T and 100 T
