Reversal of magnetic field in the large-scale $\alpha\Omega$-dinamo

In the paper investigates the question of the possibility of a reversal in the framework of low-mode model, $\alpha\Omega$-dinamo. The parameters of the MHD system in which the possible reversal of the magnetic field in the relative constancy of the velocity field are defined. There are results of numerical solution of the assumption of various type of $\alpha$-effect amplitude dependence from the radius.
