The plasma is assumed to be non-rotational, and the kinetic pressure at the edges is much smaller than inside.

"' Chart regions : "'( a ) In the top-left region, the pinching force dominates . ( b ) Towards the bottom, outward kinetic pressures balance inwards magnetic pressure, and the total pressure is constant . ( c ) To the right of the vertical line ? " W " " B " z = 0, the magnetic pressures balances the gravitational pressure, and the pinching force is negligible . ( d ) To the left of the sloping curve ? " W " " B " z = 0, the gravitational force is negligible.
