A low-pressure plasma occupies an area outside a current-carrying rod (panel a). The effect of this plasma on the magnetic field is negligible, so that (panel b, dashed line). The unperturbed plasma density is uniform, whereas the plasma temperature varies in the radial direction. This creates the pressure variation which is a potential source of the flute instability in the zone where .

Dimensionless growth rates for various values of the dimensionless gradient . The solid curves correspond to the zero viscosity. The dashed curves correspond to the case where kinematic viscosity is equal to the artificial diffusion coefficient .
