Electrode-stabilized arc in a longitudinal magnetic field
Abstract
The behavior of a finite-length, electrode-stabilized free arc in a longitudinal magnetic field is analyzed within the framework of a model of the dynamic equilibrium of the spatial position of the arc column. The model takes into account the perturbing force which generates the gas flow away from the initial position and the asymmetry of the heat supply. Conditions for the existence of a stable finite helical arc are obtained. The boundaries of the region in which transitions from cylindrical to helical arcs occur and the dependence of helix shape on electrode separations are also illustrated.
