摘要

A magnetically driven arc is produced by imposing an external magnetic field to a transferred arc. Its width is determined by the amplitude of its oscillatory motion. Its heat flux distribution can be controlled by the waveform of the magnetic field. Prediction of the heat flux distribution on the anode is necessary to apply the magnetically driven arc in industrial fields.rnThis paper describes the theoretical examination of the magnetically driven arc. A one-dimensional heat source with a Gaussian distribution is assumed to predict the heat flux distribution within the amplitude. First, the heat flux variation according to the magnetic flux density was examined under a DC magnetic field. Based on that investigation, the heat flux distributions in various AC magnetic fields were considered within the oscillatory amplitude.
