Time and azimuthal averages of the magnetic pressure components, namely, b _r ² (first column), ﹩{b}_{\theta }^{2}﹩ (second column), and ﹩{b}_{\phi }^{2}﹩ (third column), and of the gas pressure (last column) for a = −0.94 (top), a = 0 (middle), and a = 0.94 (bottom). The color scaling is the same for all spins and all components to display the differences better. The most striking difference is the small contribution of the azimuthal component b ^ϕ to the total magnetic pressure for the nonspinning BH a = 0. We note that the white region in the second column for ﹩{b}_{\theta }^{2}﹩ corresponds to regions in which ﹩{b}_{\theta }^{2}\lt 0﹩ because of numerical truncation errors in the calculation to produce this figure that arise because ∣b _θ ∣ ≪ ∣b _r ∣, ∣b _ϕ ∣.
