Abstract :
AC loss characteristics of the twisted and non-twisted Bi2223/Ag/AgMg multifilamentary tapes in the longitudinal and transverse AC external magnetic fields were experimentally investigated. The measured AC transport current loss and the AC magnetization loss in the twisted tape were affected by the amplitude and the direction of the longitudinal AC magnetic field. The magnetization loss in the transverse AC magnetic field in the twisted tape was smaller than that in the non-twisted tape. The total AC loss properties were discussed.
