Gallery of magnetic field strength and morphology in sixteen high-mass galaxy clusters selected from TNG-Cluster at z = 0. Each panel shows the central region and extends 0.2r_500c from side-to-side, giving projections of mean magnetic field strength in a thin slice of 15 kpc depth. The white circles indicate 0.1r_500c. The panels are ordered by ascending central entropy K₀, such that the strongest CC systems are in the upper left, and the strongest NCC halos are located in the bottom right. Central magnetic field strength increases rapidly with halo mass, and is higher in CC versus NCC clusters.
