Full-sky projections of the mean magnetic field along the line of sight for the simulated magnetic field and post-processing models. Upper left panel: Simulated magnetic field obtained from the simulation. Upper right panel: Modeled magnetic field, assuming a plasma beta of $\beta \equiv \frac{P_{\mathrm{th}}}{P_{\mathrm{B}}}=50$. Center left panel: Modeled magnetic field based on a fraction ℱ of the turbulent pressure. Center right panel: Modeled magnetic field based on flux freezing B ∝ ρ^2/3. Lower left panel: Modeled magnetic field, assuming a saturated turbulent dynamo scaling B ∝ ρ^1/2 down to n_e = 10⁻⁴ cm⁻³ and steeply declining beyond this density to match expectations for void magnetic fields. Lower right panel: Modeled magnetic field, assuming a saturated turbulent dynamo scaling for all density regimes.
