Equilibrium of a high-current channel in the general theory of relativity

The condition for equilibrium of a high-current channel taking account of both electromagnetic and gravitational interactions of the charges with an arbitrary drift-to-light velocity ratio is derived from the equations of Einstein’s general theory of relativity. The relative motion appearing between the electron and ion subsystems as a result of the current flow gives rise to an additional gravitational attraction between these subsystems. This is a relativistic effect that cannot be obtained in the Newtonian approximation. Zh. éksp. Teor. Fiz. 112, 385–399 (August 1997)
