# Electromagnetic mass revisited

@article{Schwinger1983ElectromagneticMR, title={Electromagnetic mass revisited}, author={Julian Seymour Schwinger}, journal={Foundations of Physics}, year={1983}, volume={13}, pages={373-383} }

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.
