摘要
本文分析计算了亥姆霍兹(Helmholtz)线圈磁场的均匀性,利用近轴条件导出了有实际意义的误差公式.最后讨论了Z=0的对称平面上磁场的分布及其均匀性.
In this paper, the homogeneity of magnetic field of Helmholtz double-coil is analysed and calculated.An error formula of practical significance is obtained by making use of the near-axis condilion.Finally, both the distribition and the homogeneity of the magnetic field on the symmetric flat at the point of Z=0 are discussed.
