本文提出了一种计算线性轴对称磁场的级数法，给出了具有两种不同媒质场域中的一般级数表达式及确定级数项系数的方法。应用本文提出的级数法计算了理想磁屏蔽的螺线管线圈磁场和空心圆柱线圈中具有铁芯的磁场，给出了计算结果及其磁屏蔽前后螺线管线圈磁场和空心圆柱线圈中具有铁芯磁场的等ｒＡ线圈。

In this paper a generalized series method to calculate the linear axisymmetricmagnetic fields is introduced. A series expansion and how to determine the term coefficients are given in a field region with two different mediums. This method has been used to solve the magnetic field problems of a solenoid coil with magnetic shield and a coil with iron core.The calculating results and equal rA lines of the magnetic fields have been given here.
