偶极子在一般外场中的能量与受力

摘要

The force on a dipole and its energy in an external field is discussed, and the properties of the force are analyzed. It is pointed out that the translation potential energy of the dipole can be defined even if in the curl field.%讨论了偶极子在一般外场中的能量及受力问题，并分析了其受力性质。文章还指出在有旋场中也可以定义偶极子的平动势能。
