It reduces the two-dimensional to a one-dimensional problem, leaving only derivatives along the fieldlines. In the core of the flow the leading-order dependence of all fluid variables along the magnetic fieldlines can be described analytically for many problems. This vorticity is clearly such as to inhibit motion of the fluid across the magnetic fieldlines (see figure 5). The axial magnetic fieldlines are thus compressed and will conserve their flux throughout the implosion. In this paper, we have explored, on the basis of laboratory experiments, the creation of a flux tube with twisted magnetic fieldlines. Knowing this one finds immediately that the inertial correction to the electric potential has a parabolic behaviour along magnetic fieldlines. The plasma pressed by the magnetic field to the internal electrode is unstable because of an unfavorable curvature of the magnetic fieldlines. Because the magnetic fieldlines resist "bending," such azimuthal asymmetries are not expected to grow and become unstable. In a magnetized plasma, we have a natural symmetry axis along the direction of the magnetic fieldlines. The poloidally closed grid lines again coincide with magnetic fieldlines. The magnetic fieldlines, however, are no longer plane. The other class comprises equilibria with straight magnetic axis and fieldlines lying in planes orthogonal to the axis. Figure 9 shows the magnetic fieldlines at the six instants. This approach is formally equivalent to the determination of magnetic fieldlines, which satisfy the same mathematical equations.
