摘要
对圆环电流在全空间的磁场分布，先用椭圆积分计算矢势，再经旋度运算求得磁场的普遍表达式，绘制磁场量值的空间分布图，而将圆环电流平面内、中心轴线上和远区的场作为特例方便地进行讨论．
To derive the universal distribution of magnetic field generated by a ring-shaped current elliptic integrals are employed for calculation of vector potential first, then the general expression of the field is obtained with the curl operation. The spatial distribution diagram for field magnitude is plotted. The field on the plane of the ring and at the central axis are discussed conveniently as special cases.
