Abstract
A new effect has been observed in a numerical simulation of relativistic self-focusing and filamentation of light beams: a coalescence of channels. The reason for the interaction of the chemicals is identified: an attraction of currents which arise in the self-focusing channels. It is demonstrated that external magnetic fields affect the channels, causing them to bend. These effects cast new light on the phenomenon of self-focusing. They raise the possibility of combining the energy from several channels into one. A mechanism for the generation of ultrastrong quasistatic magnetic fields is identified. Corresponding force effects are possible for other mechanisms for generating drive currents: radiation pressure; thermoelectric and thermionic-emission currents in laser discharges, laser beams, and intense microwave fields.
