E. ; Priest, E. R. Abstract Two-dimensional magnetohydrodynamic equilibria in the presence of an X-type natural line are investigated in the context of ideal magnetohydrodynamics. The poloidal field geometry with a neutral X-line is shown to be inconsistent with general sheared magnetostatic equilibria. Shearing of an initial potential poloidal magnetic field results in the splitting of an X-point into a current sheet with cusp-points (or Y-points in some particular cases) at its ends. The global geometry of the poloidal magnetic field produced by different types of footpoint shearing motions is discussed.
