Abstract

A solution is presented for the nearly force-free magnetic field in the inner region of an accretion disc wind, well inside the Alfven surface. This is matched to a dynamo-generated disc field and the consequences for the disc and wind structures are investigated. The radial and vertical structures of the disc are found, together with the essential properties of the wind flow. Solutions result for which the wind angular momentum loss is at least comparable to the viscous radial advection of angular momentum.
