Helmholtz 线圈与共轴三线圈磁场均匀性分析

摘要

在分析 Helmholtz 线圈磁场分布的基础上，研究等流和等径2种共轴三线圈的方法。结果表明：这2种方法均能改善 Hemlholtz 线圈磁场的均匀性，其中等流三线圈结构产生的磁场均匀性优于等径三线圈结构。%Based on the analysis of magnetic field distribution in Helmholtz coil,this paper studied the method of equal-current and equal-diameter styles of three coaxial coils in order to improve the homogeneity of magnetic field.The results show that both methods can improve the homogeneity of magnetic field and the equal-current style is better than that of equal-diameter.
