User:Maschen/Relativistic electromagnetic dipole moments

From Wikipedia, the free encyclopedia

In special relativity, the electric dipole moment d and magnetic dipole moment μ of a particle transform together under Lorentz transformations.

Dipole moment tensor

[edit]

The electric dipole moment d and magnetic dipole moment μ of a particle are unified into a single tensor[1]
