Résumé :
We construct a novel version of electromagnetism by introducing additional pure gauge degrees of freedom. Electric and magnetic fields produced by a static dyon both appear as Coulomb-like solutions in a single, manifestly duality invariant formulation without any string-like singularities. In this framework Dirac strings are only needed in order to derive the Lorentz force law from an action principle for dynamical point particle dyons. The formalism is tailor-made for a simplified treatment of black hole dyons.
