| 摘 要： | 与力学中用物体势能的空间变化率来计算力的方法相似,假定受力物体在受力方向上发生微小的"虚位移",根据不同情况下的电源供给系统的能量、系统增加的电磁场能量、静电场力和磁场力做的功之间的关系,就可方便地求出物体受到的静电场力和磁场力.

| Abstract: | The method of calculating the static and magnetic force on an object is similar to that of calculating the space change ratio of its potential energy. Suppose the object makes a virtual displacement in the forced direction, the static force and the magnetic force can be calculated according to the relationship between the power supply system, the magnetic energy, the work done by the static force and the magnetic force in different circumstances. |
