The authors present results of an experimental study 
of the heat flux within the arc spot of the copper cathode of an electric-arc 
heater with magnetic-field-induced displacement of the arc in an air 
medium - one of the most important parameters determining the 
erosion and service life of such a cathode. The investigations were 
carried out at a current strength of 110-450 A, a magnetic induction 
of 0.009-0.38 T, and atmospheric pressure.
