Gravitomagnetic Effects in the Kerr-Newman Spacetime
In this work we consider gravitomagnetic effects in the context of the Kerr-Newman solution of the General Relativity theory. Firstly, the gravitoelectric and gravitomagnetic fields are defined with the aid of the expression of the gravitational force, which is a Lorentz-type force. Then, as an application, we study the frame dragging effect, the light deflection and the gravitomagnetic time delay, exhibiting the electric charge contribution in each case and comparing the results obtained with those predicted in the Kerr spacetime.
