摘要
利用柱坐标下圆电流磁场分布和迭加原理，借助于椭圆积分求出Helmholtz线圈磁场的一般表达，分析磁场特性，而中心轴线上的场仅仅作为一特殊情况讨论。
By employing magnetic field distribution in the form of cylindrical coordinates and superposition principle, the general expression for tne magnetic field of Helmholzs' coils is achieved, with elliptic integrals.The cliaracteristics of magnetic field is analyzed. The field on central axis is treated as a special case.
