| 摘 要： | 分析了3个共轴圆线圈形成磁场的均匀性，得到了3个共轴圆线圈形成匀强磁场的条件，并且通过数值计算，全面展示3个共轴圆线圈磁场的均匀性．只要合理配置3个共轴圆线圈的大小、线圈中的电流强度和线圈之间的距离，3个共轴圆线圈的磁场在强度和均匀性方面都优于亥姆霍兹线圈的磁场。

| Abstract: | The uniform magnetic field of three coaxial circular coils is analyzed. The conditions of forming uniform magnetic field of three coaxial circular coils are obtained. By numerical calculation the uniformity is showed. It is found that the magnetic induction and the uniformity of three coaxial circular coils are much better than that of the Helmholtz coil if the size, the current intensity and the distance of coils are arranged reasonably. |
