Magnetic dipole moment of a moving electric dipole.
Am J Phys 2012 Jul; 80(7):645-647
The current density of a moving electric dipole is expressed as the sum of polarization and magnetization currents. The magnetic field due to the latter current is that of a magnetic dipole moment that is consistent with the relativistic transformations of the polarization and magnetization of macroscopic electrodynamics.
