Abstract
The performance results of the tests of a superconducting magnet coupled with a disk MHD generator in the closed cycle MHD experimental facility FUJI-1 are described. At first the performance tests of the superconducting magnet only were carried out at Toshiba, secondly the magnet was coupled with the FUJI-1 facility at Tokyo Institute of Technology and the performance tests were carried out. Both these tests have shown successful performance of the magnet.
