Abstract

We study physical aspects for a new nonlinear electrodynamics (inverse electrodynamics). It is shown that this new electrodynamics displays the vacuum birefringence phenomenon in the presence of external magnetic field, hence we compute the bending of light. Afterwards we compute the lowest-order modification to the interaction energy within the framework of the gauge-invariant but path-dependent variables formalism. Our calculations show that the interaction energy contains a long-range (${1 \mathord{\left/ {\vphantom {1 {{r^5}}}} \right.\kern-\nulldelimiterspace} {{r^5}}}$-type) correction to the Coulomb potential.
