MAGNETIC MOMENT OF PLASMA PINCH TRAVELING IN A UNIFORM LONGITUDINAL MAGNETIC FIELD,
Abstract
The magnetic moment of a plasmoid is investigated theoretically. Computation of the magnetic moment of a charged particle entering longitudinally an axially symmetric magnetic field leads to an expression for the particle velocity which depends on the form of the field. Further extension of the results shows that particles with finite radius undergo velocity dispersion dependent on their radius. These results are applied to the problem of plasmoid motion using, additionally, a system of magnetohydrodynamic equations. The problem is restricted to consideration of plasma with infinite conductivity. The magnetic properties of low and high density plasmoids are shown to differ considerably. Only low temperature plasmas are considered. The influence of thermal motion and the effect of collisons on the plasmoid behavior is discussed also and the resulting modifications are presented. The equations describing the behavior of the plasmoid form a closed set and are suitable for machine computation. (Author)
