| Abstract: | The classical orbital motion of a relativistic charged particle in electromagnetic fields is influenced by the radiation damping force as well as the Lorentz force, and the particle may be in equilibrium of forces in certain conditions. Based on the Lorentz-Dirac equation, an equilibrium condition of forces in relativistic covariant form for a charged particle (it may be a free electron in conductor) in electromagnetic fields is presented with the radiation damping taken into account. |

| Keywords: | radiation damping equation of motion equilibrium condition of forces relativistic covariance |
