Angular power spectrum for four models of the scaling of the magnetic field with the halo masses: (i) B₀ = const. in solid red; (ii) an increase of the magnetic field for galaxies, i.e. at masses lower than 10¹³ M_⊙ as given by Eq. (15) (dashed blue); and a combination of increased magnetic field for galaxies, Eq. (15), with a power law for massive clusters, Eq. (14), where (iii) γ = 0.25 (dotted green), and (iv) γ = 1 (dash-dotted orange).
