The authors have developed a wide heat source by imposing an alternating magnetic field perpendicularly to a transferred arc. In this paper, the deformation of the arc root on the anode is examined theoretically. In a uniform magnetic field, the arc root area increases with the increased arc displacement from the center. The increase of the area decreases the heat flux density. The application of the non-uniform magnetic field is discussed to prevent the decrease of the heat flux density. If the reversed magnetic field is applied to the arc near the anode, the incident angle of the arc to the anode becomes large (close to π/2). In other words, the application of such a non-uniform field might suppress the increase of the area of the arc root. Consequently, it might suppress the decrease of the heat flux density. Theoretical prediction of the effect of the non-uniform field is confirmed experimentally.
