The question of creating a plasma trapped by a magnetic field is always subject to the mean free paths of the particles, and the ability of the field to contain even particles that would tend to escape the field, through multiple collisions. A charged particle goes in a circular motion around the magnetic flux lines, and its motion parallel to the lines is only affected by an increase in the value of the magnetic field since this would cause the magnetic flux lines to come closer. When this happens, the particle is reflected. This configuration happens in the magnetosphere, the plasma around the earth trapped inside Earth's magnetic field eg. ( The Van Allen Radiation Belt ). At atmospheric pressure, the particles undergo collisions in their motion around the magnetic flux lines, and each collision makes them "jump" from one "circle" to another, causing them to diffuse perpendicular to the magnetic field, and perpendicular to the ground core of our solenoids, a thing that was impossible without collisions because of the constraining property of the magnetic field. The electrons are not completely confined, their density in the region of containment is still orders of magnitude higher than outside that region, but may have been of concern when Steven Mark had a visit from the Nuclear agency in the USA. When particles are confined by a magnetic field, they circle in a characteristic radius equal to the gyroradius( https://en.wikipedia.org/wiki/Gyroradius )of that couple magnetic field/particle. Unless you have tremendously high magnetic fields, or impossibly small speeds ( to ignite a plasma, electrons need speed, or they recombine fast), this gyroradius will be a lot more than microns. This means, finally, that your particles are not at all contained by the magnetic field, but rather by the speed of the decay of the plasma, they will usually recombine faster than they will escape the field. In the TPU application of plasma, this fast recombination is not the case, the Atmospheric Dielectric Plasma, or DBD, which is bi-temperature, non-equilibrium plasma, is a cold gas plasma. This plasma consumes a lot less energy than the hot plasma and has proven plasma lifetimes high enough to observe "balls" of plasma, drifting together with the gas flow (simple mechanical flow) until a few tenths of centimeters. These "balls" of plasma are mostly rich in radicals, i.e. species, created by the plasma, that "should not exist" in the neutral gas because they have very short lifetimes. These radicals are used in plasma chemistry, material transformation, and why it is used to treat anything that can be "treated" by such radicals. I have shown in the TPU that the core of the solenoids is a plate of a capacitor “C1”, and that the inside surface of the solenoid coils is the other plate of “C1” (collector core is perpendicular to the solenoid coil, no induction, only capacitance). The way that the solenoid coils are connected to one another, a type of resonant delay line is created as the plasma on the surface of the dielectric passes through the solenoids. This delay creates movements of around a few Hz through the solenoids, this is the washboard effect that was talked about as movement felt within the TPU of Steven Mark.
