Main panel: Radial profiles of the plasma beta parameter β_P at z = 0 for all TNG-Cluster halos, colored according to CC state. Thin lines show individual clusters, while the three thick lines show median stacks of SCC, WCC, and NCC clusters. The shaded bands around the median show the 95% confidence intervals. Lower panels: Maps of the thermal pressure (left) and magnetic pressure (right) of one individual SCC halo ans an example. Both maps show the central region with r < 0.2r_500c for a slice with depth 15 kpc. The overall pressure budget is dominated by the thermal pressure for both CCs and NCCs. The β_P profiles for WCCs and NCCs are flat with average values of β_P ∼ 900. SCCs have a small dip in the core and a excess at 0.1r_500c. However, these trends are rather weak.
