## Numerical simulation and experiment on atmospheric arc in external and self magnetic fields

Experiments on interaction of atmospheric pressure arcs with external DC and oscillating magnetic fields have been conducted at PPPL. The studies can have important implications with regard to understanding of arc deflection and instabilities in industrial devices, such as arc furnaces. Good qualitative agreement with experiment has been achieved with a simple analytical two parameter model for the behavior in steady-state. The model gives unexpectedly high values for the mass density of the arc plasma. The authors will present the results of extending the model to a numerical simulation with the inclusion of the terms of viscous drag and selfmore »
