| 摘 要： | 关于两个回路L1和L2的互感系数只有一个,即M12=M21,理论证明方法除普通物理电磁学教材中的证明方法外,还有另两种证明方法,即运用磁矢势和磁偶极子来证明互感系数M12=M21. |
| 关 键 词： | 互感系数 磁矢势 磁偶极子 圆电流 |

| Abstract: | There is only one coefficient of mutual inductance about two round roads L_1 and L_2,i.e.M_(12)= M_(21).The theoretical testimonial methods include the methods appearing in the book of electromagnetism,but here the other two methods werwgiven.This article uses magnetic vector potential and magnetic dipole to prove circular electricity M_(12)=M_(21). |
| Keywords: | coefficient of mutual inductance magnetic vector potential magnetic dipole circular electricity |
