Magnetically-induced CMB TT (top left), TE (top right), EE (bottom left), and BB (bottom right) power spectra. The solid lines represent primary CMB anisotropies, the dotted lines represent magnetically-induced compensated scalar modes (except for the BB panel, where it represents the lensing contributions and the solid line represents primary tensor modes with a tensor-to-scalar ratio of r = 0.1), the dashed lines represent vector modes, whereas the dot-dashed lines represent magnetically-induced compensated tensor modes. We consider PMFs with B_{1 Mpc} = 4.5 nG and n_B = −1.
