摘要：

New experimental data on the effective 'thermal' density of a current in the nonstationary arc spot on the copper cathode of an electric-arc heater of a gas and its dependence on the magnetic field have been obtained by thermophysical methods. Results of the investigation can be used for thermal calculations of electrodes for the purpose of increasing their service life.
