Equations of electrodynamics in the context of the Brans-Dicke theory.

Abstract

We consider the Brans-Dicke theory of gravity, assuming a weak gravitational field generated by a material source with a rotating motion. In this context, we find the equations of electrodynamics, verifying the gravitational effects, such as gravitomagnetic effects, that contribute to the production of electric and magnetic fields. The equations obtained are compared with those predicted by general relativity. Then, some particular results are discussed.
