Beschreibung:
<jats:p>An electric arc may be displaced by a magnetic field, by a gas flow and also by unsymmetric heating and cooling. This occurs for instance, if a portion of the wall of a wall-stabilized arc is heated. For this case the displacement is investigated theoretically for steady state conditions. Furthermore the deflection is calculated for an explicit dependence of electrical and thermal conductivity upon a space variable. The different possibilities considered in theory are realized experimentally. The measurements are in good agreement with the theoretical results.</jats:p>
