Dependence of the heating efficiencies on the magnetization ﹩{\sigma }_{w}﹩ (normalized to the enthalpy density), with a layout similar to that of Figure 12: (a) electron total, ﹩{M}_{T{\rm{e}},\mathrm{tot}};﹩ (b) electron adiabatic, ﹩{M}_{T{\rm{e}},\mathrm{ad}};﹩ (c) electron irreversible, ﹩{M}_{T{\rm{e}},\mathrm{irr}};﹩ (d) proton total, ﹩{M}_{T{\rm{i}},\mathrm{tot}};﹩ (e) proton adiabatic, ﹩{M}_{T{\rm{i}},\mathrm{ad}};﹩ (f) proton irreversible, ﹩{M}_{T{\rm{i}},\mathrm{irr}}﹩. We fix ﹩{T}_{{\rm{e}}}/{T}_{{\rm{i}}}=1﹩ and ﹩{m}_{{\rm{i}}}/{m}_{{\rm{e}}}=1836﹩ and vary the magnetization ﹩{\sigma }_{w}=0.1﹩ (green), 0.3 (purple), 1 (brown), 3 (magenta), 10 (black); the legend is located in the upper part of panel (b). Points in panels (a)–(c) are colored according to ﹩{\theta }_{{\rm{e}},\mathrm{up}}﹩ (color bar is to the right of panel (c)), and points in panels (d)–(f) are colored according to ﹩{\theta }_{{\rm{i}},\mathrm{up}}﹩ (color bar is to the right of panel (f)).
