A fully self-consistent nonlinear dynamo is studied in the limit of the low kinetic Reynolds number by adopting a simplified statistical model. Governing equations for the evolution of a mean magnetic field and correlation functions of fluctuating magnetic fields are derived for arbitrary values of
## Abstract It is shown in an idealized Ξ±Οβdynamo model that a finite flux density not only is able to prevail against its own backreaction on the generating mechanism but can even make the dynamo more responsive to excitation and enable it to run subcritically.
