Аннотация
The occurrence of the magnetic fields of galaxies is usually explained by the action of the dynamo mechanism. Nevertheless, at distances of the order of 15-20 kpc, the action of the dynamo is significantly weakened. The magnetic field in these regions can be described by other mechanisms, for example, magnetorotational instability. In this work, solutions that correspond to both the mechanisms of dynamo and magnetorotational instability have been found.
