In this paper, the in‰uence of arc current on vacuum arc behaviors of a new AMF electrode with single coil structure was investigated at long gap distance of 40 mm. A high-speed charge couple device (CCD) video camera was used to observe the arc behaviors. Two groups of arc modes were featured: 1) diŠuse arc modes including multi-cathode spots arc, high current diŠuse arc and high current diŠuse column arc. 2) constricted arc modes including anode plasma jet with local concentration of many
