亥姆霍兹线圈轴平面磁场分布的实验研究

Experimental Study on the Magnetic Distribution of Axial Plane Magnetic Field about Helmholtz Coil

根据毕奥—萨伐尔定律,导出了亥姆霍兹线圈轴平面磁场的分布解析表达式,以解析表达式为基础对亥姆霍兹线圈实例进行了数值计算,并与实验结果做一比对,最后,对一些特殊场点作了讨论。

Based on Biot-Savart law,a analytic expression ol axial plane magnetic field about Helmholtz coil is given.For the certain current Helmholtz coil,the numerical result is obtained by the numerical calculation on the foundation of the analytic expression, and the comparison with the experimental results is made, some spe-cial condition is discussed.
