Abstract

Characteristic features of the Darwin (non-radiative) description of electromagnetic fields are considered. Criteria for the physical adequacy of the considered formalism are obtained using a self-consistent approach to representing non-linear processes in rarefied plasma. Use of the proposed adequacy estimates of non-radiative approximation is demonstrated based on a numerical analysis of the Weibel instability.
