Research Abstract

The analysis and the experiment considered the influence of trapped magnetic flux on the bulk by the fluctuation magnetic field of a rotating machine which poses a problem by development of a superconductivity bulk motor. It was shown that these fluctuation magnetic field affects influences of a few on trapped magnetic flux of bulk. And, it was able to be shown that there is sufficient effect by arrangement of the shielding coil for the trapped magnetic flux suppression of bulk.
