Examples of uniformly moving charge distributions that possess conserved electromagnetic stress tensors are exhibited. These constitute stable systems with covariantly characterized electromagnetic mass. This note, on a topic to which Paul Dirac made a significant contribution in 1938, is dedicated to him for his 80th birthday. 

Fermi and electromagnetic mass

Fermi’s analysis of the contribution of the electromagnetic field to the inertial mass of the classical electron within special relativity is brought to its logical conclusion, leading to the

Classical electron theory and conservation laws

To the substantiation of the radiation damping force

The differential law of conservation of energy-momentum density for an arbitrary moving relativistic charge is formulated in the most general form. Based on it, the radiation damping force is derived

Electromagnetic (self-) interactions in relativistic Schrödinger theory

The Relativistic Schrodinger Theory (RST) is applied to a system of N particles with electromagnetic interactions. The gauge group is U(1) × U(1)... × U(1). By exploiting the mathematical structure...

2 Magnetic Pole plus Electric Charge

The term “hidden momentum” was introduced by Shockley [1] in 1967 to describe the small amount of net mechanical momentum that must exist in systems “at rest” that have nonzero electromagnetic field

Relationships Between Electromagnetic and Mechanical Characteristics of Electron

A relationship between electron charge and electron mass was established based on energy relations. A conclusion was drawn about solely electromagnetic nature of mass. Hence, the generalized magnetic


It is shown that within classical electromagnetism there is at least one, and very likely many other, particle behaviors that are innately free of singular self-action, provided the bare charge is
