摘要
以毕奥-萨伐尔定律为基础,建立亥姆霍兹线圈以及格拉斯磁环中心磁场分布模型,并计算了它们内部的轴向磁感应强度分布,绘出了空间分布图,分析了轴向磁感应强度与x、y坐标的关系,分析结果得到了亥姆霍兹线圈和格拉斯磁环内部匀强磁场分布区域,通过比较得到格拉斯磁环内部的匀强磁场区域比亥姆霍兹线圈内部的匀强磁场分布区域更大的结论。
Based on the biot-savart law, distribution models of the magnetic field produced by Helmholtz coils and magnetic ring of Glass are set up. The distribution of the internal axial magnetic induction intensity is calculated, and distribution diagrams is given. The relation between the magnetic induction intensity and coordinates is analyzed. The magnetic field homogeneity of magnetic ring of Glass is compared with that of Helmholtz coils. It is found that the former is much better than the latter on many aspects, such as the homogeneity, the width of homogeneity area.
