Evolution of 〈log β〉 (top) and total energies (bottom) for three different phases of the gas. The blue, orange, and green lines show the gas in a low (−2 < log(n/cm⁻³) ≤ 0), medium (0 < log(n/cm⁻³) ≤ 2), and high (2 < log(n/cm⁻³) ≤ 4) density phase, respectively, for model T (left) and model R (right). In the top plots, the dashed black line corresponds to 〈log β〉 = 0, which is the critical value. Above this value, the gas is thermally dominated, while below it, it is magnetically dominated. For the bottom plots, circles represent the thermal energy, and triangles correspond to the magnetic energy. The dashed red line represents the onset of star formation. The shaded regions correspond to the standard deviation.
