We construct self-similar inflow-outflow solutions for a hot viscous-resistive accretion flow with large-scale magnetic fields that have odd symmetry with respect to the equatorial plane in Bθ and even symmetry in Br and Bφ. Following previous authors, we also assume that the polar velocity vθ is non-zero. We focus on four parameters: βr0, βφ0 (the plasma beta parameters associated with magnetic field components at the equatorial plane), the magnetic resistivity η0 and the density index n = -dlnρ/dlnr. The resulting flow solutions are divided into two parts, consisting of an inflow region with a negative radial velocity (vr < 0) and an outflow region with vr > 0. Our results show that stronger outflows emerge for smaller βr0 ( ≤ 10^–2 for n > 1) and larger values of βφ0, η0 and n.
