DATA & FILE OVERVIEW
--------------------

This dataset contains: arc images and the corresponding voltage–current waveforms used in the following studies:

Arc cooling study
External magnetic field: 0 and 40 mT
Contact opening speed: 10–500 mm/s
Arc runner influence study
External magnetic field: 40–130 mT
Contact opening speed: 100–500 mm/s
Arc runner angle: 30–120 degrees


Due to the large volume of experimental images and waveforms, two representative experimental results have been included for each experimental condition. If further experimental results are required, please contact the author at: yanmingli163@163.com.
