磁偶极子和电流
Magnetic dipoles and electric currents
摘要：
我们讨论了电偶极子和磁偶极子概念之间的一些相似之处和不同之处。然后，我们考虑磁偶极子和电流回路之间的关系，并表明，在一个点状电路的限制，他们的磁场重合。介绍是访问的本科生与经典电磁学的基本思想的知识。
英文摘要：
We discuss several similarities and differences between the concepts of electric and magnetic dipoles. We then consider the relation between the magnetic dipole and a current loop and show that in the limit of a pointlike circuit, their magnetic fields coincide. The presentation is accessible to undergraduate students with a knowledge of the basic ideas of classical electromagnetism.
