SUMMARY:

In the perspective of explaining what we call weak field approximation in General Relativity, it fell to us to carry out studies to develop the equations of Einstein Field. Within this issue we were able to determine some predictions of the Theory of General Relativity with this approximation, effects which are described in the so-called gravitational effects, such as gravitomagnetic time delay, the so-called de Sitter effect (precession of geodesics) and the Lense-Thirring effect (drag of inertial frames). Other study bases helped us in the development of this work, such as the so-called gravitomagnetic field, whose purpose is to analyze which currents matter (no charge) could produce gravitational effects similar to electric currents produced in the field of electromagnetism and we are also based on the consequences
gravitational forces linked to the rotation of massive bodies within what values the concepts of General Relativity. To demonstrate gravitational effects, we take as a starting point the Gravity Probe B test, an audacious project that began in the 1990s of 60, and proved the theory of drag of inertial reference frames, the gravitomagnetic delay of clocks and the precession of geodesics. Thus, the results of this project were presented in 2011 with an accuracy very close to what TRG dictates.
