力学模型在磁学中的应用一例

An Example of a Mechanics Model Applied to Magnetism

本文所介绍的力学系统与铁磁材料在外磁场中的行为十分相似，即二者的相图十分相似；力学系统的势能类似于铁磁材料的自由能．

The mechanics system described in this article is very similar to a ferro-magnetic material's behavior in an outer magnetic field. Their phase diagram is very similar; the potential energy of the mechanics system is similar to the free ener gy of the ferro-magnetic material.
