Ac Losses of Ag sheathed Bi-2223 High-$T_{c}$ Superconducting Wire
은 피복 Bi-2223 고온 초전도 선재의 교류손실
Abstract
AC losses per cycle properties at 77K have been investigated on the Ag sheathed Bi2223 wire through two kinds of measuring methods(transport method and magnetic method). In case of transport method, the absolute value of losses agree with the results of Norris theory(strip and ellipse). In case of 19-filamentary tape, AC transport losses almost agree with those of magnetic method. In case of 1-filamentary tape, However, AC losses of magnetic method is smaller than AC transport losses
