We present the results of a measurement analysis aimed at investigating, from a phenomenological point of view, the plasma arc behavior in the presence of rotating magnetic field. In order to obtain such data, an experimental setup was assembled in our laboratory, consisting in two electrodes connected to a welding machine and three electromagnets. A digital photo camera is used to observe the phenomenon and electrical quantities are measured by means of an oscilloscope. The experiments indicate a significant interaction between the plasma and the magnetic field. Finally, measurement results are shown and discussed.

Abstract
We present the results of a measurement analysis aimed at investigating, from a phenomenological point of view, the plasma arc behavior in the presence of rotating magnetic field. In order to obtain such data, an experimental setup was assembled in our laboratory, consisting in two electrodes connected to a welding machine and three electromagnets. A digital photo camera is used to observe the phenomenon and electrical quantities are measured by means of an oscilloscope. The experiments indicate a significant interaction between the plasma and the magnetic field. Finally, measurement results are shown and discussed.File in questo prodotto:
