We report on the discharge behaviour and the mode transition observed in a magnetically constricted anode device. With an increase in pressure, the central droplet shaped glow shrunk and abruptly switched to peripheral glow mode for pressure above 5×10−2 mbar. This transition is observed when the width of the droplet shaped glow at the anode approaches the diameter of the central magnet. The mode transition is observed as a sudden jump in the discharge current, which obeys a different power law than the previous discharge mode. Further, this new mode is observed to accompany the global oscillations in the range of few kHz.
