Abstract
DIRAC has recently1 proposed a generalization of his new theory of electromagnetism so as to permit vortical streams of the electrical charge. The vortical motion has been introduced by redefining the potentials in a more general manner. Dirac has then framed two stationary principles, both of which lead back to the Lorentz equation of motion for an electric charge, with, however, the ratio, m/e = k, only occurring in it. The first of these stationary principles has for its action density where the potentials are assumed to be of the form
