在与零压力均匀轴向磁场差别不大的各种情况下获得了水磁平衡。确定这些平衡稳定性的标准是通过能量原理找到的。特别是，如果存在螺旋不变场，则可以找到具有非零压力和净轴向电流的稳定平衡。
Hydromagnetic equilibria are obtained for a variety of situations which differ little from that of a zero pressure uniform axial magnetic field. Criteria for ascertaining the stability of these equilibria are found by means of an energy principle. In particular, if helically invariant fields are present, stable equilibria with nonzero pressure and net axial current can be found.
