    "abstract": "Here diffusion and Ware pinch are analyzed as opposed effects for plasma\nconfinement, when instabilities are not considered. In this work it is studied\nthe equilibrium inductive electric field where both effects annul each other in\nthe sense that the average normal velocity is zero, that is, marginal velocity\nconfinement is reached. The critical electric field defined in that way is\nstudied for different values of elliptic elongation, Shafranov shift and\ntriangularity. A short complementary analysis is also performed of the\nvariation of the poloidal magnetic field along a magnetic line.\nMagnetohydrodynamic transport theory in the collisional regime is used as in\nrecent publications. Axisymmetric and up-down symmetry are assumed",
