Density contour for an expanding galactic bubble in a magnetized halo-disk medium at t = 10 Myr. Each panel displays two morphologies of the disk under investigation: a thick disk on the left and a thin disk on the right. The galactic wind has a mass flux of Ṁ = M_⊙ yr⁻¹. Top-left panel: dipole B = 10⁻⁴ Gauss, top-right panel: dipole B = 10⁻² Gauss, bottom-left panel: dipole B = 1 Gauss, bottom-right panel: a dipole component with (B₀ = 10⁻² Gauss and uniform field B = 10⁻⁶ Gauss).
