Abstract

We present an approach to compute the electric and magnetic dipole moments of an electron by using polarization and magnetization parts of the Dirac current. We show that these dipole moment expressions obtained by our approach in this study are in agreement with the current experimental results in the literature. Also, we observe that a magnetic field plays an important role in the magnitude of the electrical dipole moment of the electron.
