Break arcs are generated in a DC48V and 10A resistive circuit. The external transverse magnetic field of a permanent magnet is applied to the break arcs. The position and shape of the break arc are investigated. As a result, it is confirmed that the cathode spot region was shifted upward earlier than the anode spot region. This result shows that the cathode spot region is easily driven by the transverse magnetic field than the anode spot region.
