由Bi（2223）Ag带制成的螺线管的临界电流在77 K下的临界电流-磁场特性中具有高各向异性，该临界电流特别地由磁场的径向分量确定，该径向分量在线圈凸缘附近较大。介绍了利用辅助绕组（如铜绕组）部分补偿高温超导（HTS）线圈径向磁场分量的基本思想。对模型线圈的大量数值计算结果表明，可以预期临界电流增加50%以上。
The critical current of a solenoid made of Bi(2223)Ag tape with a high anisotropy in the critical current - magnetic field characteristic at 77 K is determined in particular by the radial component of the magnetic field, which is large close to the coil flanges. The original idea of utilizing supplementary (e.g. copper) windings to compensate partially the undesired radial magnetic field component of the high-temperature superconducting (HTS) coil is described. The results of extensive numerical calculations on the model coil indicate that an increase of the critical current of more than 50% can be expected.
