摘要
为获得二同轴方形载流线圈间相互作用磁力，计算出了线圈间的互感系数。将虚功原理作为一种简捷方法加以运用，对该力极值位置进行了分析和图示。讨论平面内二同心方形线圈载流时一线圈不受磁张力的优良力学状态。
In order to achieve the magnetic force between two coaxial square coils canying currents,the coefficient of mutual induction is computed.Then principle of virmal work is employed as a handy way to calculate the force.The extreme value property of the force is analyzed and illustraed.The preeminent mechanical state where no magnetic tension force exerts on either of the two concentric square coils carrying currents is described.
