Magnetic dipole moment of a moving electric dipole

Preprint English OPEN
Hnizdo, V.;

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 polarizat... View more

    2 We use Gaussian units since the relativistic aspects of relations among the dipole moments are displayed most clearly in these units.

    6 This situation is somewhat paradoxical since we shall see that, unlike the acquired electric dipole moment, the acquired magnetic dipole moment is not a relativistic effect.
