我们通过实验研究了暴露于垂直于宽表面的外部交流磁场的 Bi2223 超导线的交流损耗。通过使用堆叠到一层或几层的直导线的短样本来测量交流损耗，并与基于通常临界状态模型的传统理论进行比较。结果表明，垂直场中堆叠线的交流损耗可以渐近地估计为具有与线宽度和堆叠线中的总J c 相同厚度的超导板的交流损耗。
We experimentally studied ac losses in Bi2223 superconducting wires exposed to an extemal ac magnetic field perpendicular to the wide surface. The ac losses were measured by use of a short sample of straight wires stacked to one or some layers and compared with the conventional theory based on the usual critical state model. As a result, it is shown that the ac losses of the stacking wires in the perpendicular field can be asymptotically estimated as those of superconducting slabs with the same thickness as the wire width and an overall J c in the stacked wires.
