Abstract

AC loss characteristics of the twisted multifilamentary high temperature superconducting tape with different twist pitches in external AC longitudinal magnetic field as well as those of the nontwisted tape were experimentally investigated. We measured the AC transport current loss and the AC magnetization loss in the twisted and nontwisted Bi2223 multifilamentary tapes in the external AC longitudinal magnetic field. The measured transport loss and magnetization loss in the twisted tapes were affected by the amplitude and the direction of the AC longitudinal field. It was also shown that the AC losses in the tapes under the external AC longitudinal field depended on the twist pitch.
