Can You Control a Plasma Arc with a Magnetic Field?
Can you rotate or control a pulsed plasma using a magnetic field? And what happens if the pulse is only about 100 nanoseconds long?
In this video, I respond to a viewer question about gliding arcs, pulsed plasmas, magnetic fields, and whether it is possible to control ignition, reignition, and arc motion on very short timescales.
I walk through the basic sequence of atmospheric-pressure discharge formation: electron avalanche, streamer, spark, and arc. Then I explain different ways to influence or steer plasma, including gas flow, magnetic fields, electrode geometry, pressure gradients, laser…
