The static Einstein-Maxwell field equations will be investigated in the presence of both electric and magnetic fields. The sources or bodies are assumed to be of finite size and to not affect the connectivity of the associated space. Furthermore, electromagnetic and metric fields are assumed to have reasonable differentiabilities. It will be proved that the electric and magnetic field vectors are constant multiples of one another. If, furthermore, the variational derivation of the Einstein-Maxwell equations is assumed, it will be pointed out that if a suspended magnet be electrically charged, then it must experience a purely general relativistic torque.
