Overview

Experiments show magnetic field alters plasma dynamics in liquid interfaces, suggesting control over plasmoid formation.

Key Points

  • This research aims to explore how a time-varying magnetic field affects plasma discharges at a liquid-air interface.
  • Used conductive sodium chloride solutions to create plasma discharges.
  • Applied a time-varying magnetic field using a Helmholtz coil.
  • Conducted spectroscopic measurements to analyze plasma emissions.
  • Lorentz force significantly alters the jet dynamics, converting vertical jets to horizontal arcs.
  • Atmospheric plasmoid formation is inhibited under the influence of the magnetic field.
  • Distinct liquid surface flow patterns are generated around the cathode due to lateral plasma motion.
