磁偶极子是研究物质磁性时最初由磁荷假说引入的一个基本模型,随着物理学的发展人们逐渐认为“它不太符合磁介质的微观本质”[1],因而被有的人戏称为“科学上的老古董”,甚至有人认为今天还用磁偶极子模型是个错误,更有人提出疑问,为什么不用磁畴模型而用磁偶极子模型来研究磁
Magnetic dipole is a basic model originally introduced by the magnetic charge hypothesis when studying the material magnetism. With the development of physics, people gradually think that “it is not in conformity with the microscopic essence of magnetic media” [1] Some people even think that it is a mistake to use the magnetic dipole model today. Some people even raise questions as to why the magnetic dipole model should not be used to study magnetic
