Development of Compact Magnet with magnetic Flux Density of 3.1 Tesla
Hitachi has announced the development of prototype of a super compact magnet which fits into an individual palm but offers a powerful magnetic flux density of 3.1 tesla. The new magnet is made of a small refrigeration part which is attached to cylindrical vacuum chamber containing a high temperature superconductor made of gadolinium-barium-copper-oxide substance which has zero resistance when it is cooled to -183 degrees Celsius. The magnet comes in a form factor of 23.15 x 11.5 x 6 cm, weighing only 1.8 kg.
The magnet’s refrigeration component has only 23 watts of power consumption which is equivalent to fluorescent lamp with operational life that extends to more than 15,000 hours. The commercial version of the newly developed magnet system will be available within 5 years time and its first application is expected to be in regenerative medical research.
