亥姆霍兹线圈磁场均匀区的理论计算

Theoretical Calculation of Megnetic Equal Region Inside Helmholtz Coil

本文从毕一萨定律出发，导出了过亥姆霍兹线国轴线平面内任意一点的磁感应强度表达式，并在计算机上算出了任意一点的磁感应强度的大小及与线圈中心点相比的相对误差，并以图形形式画出了亥姆霍线国内的磁场均匀区。

The representation of magnetic induction inside Helmholtz Coil is induced by Biot-Safer Law. The magnitude of magnetic induction and its relative error of any point compared with that of Coil center is calculated on Computer. The result of magnetic equal region in side Helmholtz Coil is given in graphic form.
