Abstract: In the dynamic model -dimensions are simulated reversions of the magnetic field with a varying intensity of the -generator. The change of the \alpha$-generator intensity as a result of synchronization of higher modes of the velocity field and the magnetic field is regulated by a function Z(t) with a power kernel. Dynamo modes are obtained for two types of radial component in the scalar parameterization of the $\alpha$-effect. The results were analyzed depending on the change in the exponent of the kernel of the function Z(t), also a comparative analysis with the results of the study [10], where the exponential kernel of the function Z(t) was used.

Keywords: large-scale dynamo model, $\alpha \Omega$-dynamo, magnetic field, inversions.
