The geometry of magnetic fieldlines in magnetogeostrophic flows
It is proved that the only circulation preserving magnetogeostrophic flows whose current density is lamellar, and bears a constant on a current density vector have (1) a plane motion of constant current density (on which certain unsteady potential motions may be superposed) and (2) a particular circular helical motion.
