Gravitomagnetic clock effect

The gravitomagnetic clock effect is a phenomenon predicted by general relativity, specifically relating to the influence of a rotating massive object on the passage of time for clocks positioned in its gravitational field. In general relativity, gravity is not just a force but a curvature of spacetime caused by mass. When an object is rotating, it creates a "gravitomagnetic" field, analogous to the magnetic field created by a moving electric charge.
