The possibility of generating a magnetic field at a large distance (10-15 kpc) from the center of the galaxy has been investigated. The magnetic field can be generated both by the dynamo mechanism, considering nonlinear effects, and by magnetorotational instability. Presumably, the nonlinear effects of the dynamo mechanism play a more significant role at this distance. Keywords: Magnetororotational instability, dynamos, galaxies, magnetism.
