Evolution of transverse magnetic fields B_⊥ for the runs in Table 4 with nonrelativistic CRs. The results are similar to the runs with relativistic CRs (see Section 4); we include two of these runs for comparison. Inset: saturated magnetic field ﹩{\left({B}_{\perp }/{B}_{0}\right)}_{\,\rm{sat}\,}﹩ vs. effective anisotropy parameter ξ_eff for these runs (triangles for monenergetic CRs, squares for power-law CRs; the colors are similar to those in the legend). The gray dashed line represents Equation (17).
