摘　　要：研究非密绕球形线圈内部的磁场均匀性质.从圆形电流线圈轴线上的磁场出发,利用叠加原理和Mathematica软件的计算和符号推导功能,得到一个关于线圈内部磁场均匀性与其匝数的定量关系式,在此基础上通过实例说明设计球形线圈磁场均匀区的方法.The homogeneous property of magnetic field in spherical coils is investigated.From the magnetic field along the axis of circular current coil,we get the quantitative relation between the windings and homogeneity of the homogeneity of magnetic field in the spherical coils with the help of the superposition principle and symbolic operation of Mathematica.Through examples,the method to design homogenous area of magnetic field in spherical coils is explained.This study will provide theoretical help for constructing large uniform-magnetic-field workroom.
