We discuss several similarities and differences between the concepts of electric and magnetic dipoles. We then consider the relationship 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 knowledge on the basic ideas of classical electromagnetism.

Abstract

We discuss several similarities and differences between the concepts of electric and magnetic dipoles. We then consider the relationship 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 knowledge on the basic ideas of classical electromagnetism.
