摘要
讨论了在激发磁场的电流保持不变时和束缚磁荷作为磁场的源不变时 ,两种情况下磁场的相互作用能 .结果与静电场类似 ,两种情况的互作用能中都含有相互磁化 ,致使物体磁化状态改变作的功 .
The interaction energy of magnetostatic field is discussed in two cases, namely when the current sources of magnetic field are fixed and the bound magnetic charges as source of magnetic field are fixed. The results are completely analogous to electrostatic results. The interaction energy in two cases all include the work done in changing magnetization.
