Back Reaction to the Spectrum of Magnetic Field in the Kinetic Dynamo Theory
Back Reaction to the Spectrum of Magnetic Field in the Kinetic Dynamo Theory
We take account of the lowest order back reaction on a fluid and modify the Kulsrud-Anderson equation, ∂tεM = 2 γεM, obtained in the kinetic dynamo theory, where εM is the energy density of the magnetic field. We apply our results to certain astrophysical stages where the magnetic field is …
