The Influence of Parallel Magnetic Field on Magnetization Loss in a Bi-2223 Tape

수평자계가 Bi-2223테이프의 자화손실에 미치는 영향

Magnetization loss of a Bi-2223 tape in magnetic fields parallel to the tape surface was measured by a magnetization method. The results indicate that the magnetization loss is hysteretic because the measured loss agrees well with calculated one from a critical state model. In the full field penetration case the magnetization loss increases with the frequency but in the partial field penetration case the influence of the frequency is opposite.
