Gravitoelectromagnetism, abbreviated GEM, is a set of formal analogies between the equations for electromagnetism and relativistic gravitation. More specifically, it is an analogy between Maxwell's field equations and an approximation, valid under certain conditions, to the Einstein field equations for general relativity. Gravitomagnetism is the kinetic effects of gravity, in analogy to the magnetic effects of moving electric charge. The most common version of GEM is valid only far from isolated sources, and for slowly moving test particles.
