The dissipative function in magnetic systems

To the theory of electromagnetic radiation by fast moving body

“…The solution of the (21) for the external problem of the mathematical physics i.e. ra  leads to a solution as an Lienar-Vihert's potential [1] and in my researches [20][21][22][23][24][25], but taking into account not a single electron, but their ensemble, the density of the charge distribution in which there is q  . It means that,…”
