Electromagnetic mass and charge of electrons at relativistic speed

Abstract

The concept of electromagnetic mass was developed in the last half of the nineteenth century and has been studied till date from various approaches. Here we have discussed some of those approaches and later we have focused on the mass corresponding to the charge of an electron in the framework of the spinning sphere of electrons. It is shown how the charge and the mass contribute together to the total energy of electrons. The dependence of the charge and the mass on the velocity is also discussed.
