The axisymmetric, incompressible, viscoresistive magnetohydrodynamic equations for purely poloidal currents I(r,z) are transformed into three coupled scalar partial differential equations. These show that finite {∂}I/{∂}z acts as a volumetric source of fluid ``vorticity'' which drives strong poloidal flows (jets).
