摘要
同轴线圈的互感系数与其相互作用能和相互作用力密切相关,是物理学的基础理论问题,也具有工程应用价值。该文采用LCR数字电桥先测量线圈N_(1)和N_(2)的自感LN_(1)和LN_(2);然后根据自感和互感的关系,得到不同距离处的互感系数M;最后利用Origin8.0强大的数据处理功能模拟出互感系数与相对位置之间的关系表达式,实验数据曲线与拟合曲线拟合系数达到99%以上,与理论积分近似计算的结果表述一致。实验测量互感的方法可以减少繁琐的积分计算,也可以得到互感系数与相对位置之间的函数关系。
The mutual inductance of coaxial coil is closely related to its interaction energy and interaction force.It is not only a basic theoretical problem in physics,but also has engineering application value.In this paper,LCR digital bridge is used to measure the self-inductance LN_(1) and LN_(2) of coil N_(1) and N_(2);then,according to the relationship between self-inductance and mutual inductance,the mutual inductance coefficient M at different distances is ob‐tained;finally,the relationship expression between mutual inductance coefficient and relative position is simulated by using the powerful data processing function of Origin8.0.The fitting coefficient of experimental data curve and fitting curve is more than 99%,which is consistent with the result of approximate calculation of theoretical integral.The method of measuring mutual inductance by experiment can not only reduce the tedious integral calculation,but also obtain the functional relationship between mutual inductance coefficient and relative position.
