Evolution of transverse magnetic field B_⊥ for the runs PLI:5-400:p⁻³, PLI:5-400(p⁻⁴), and PLI:5-400:p⁻⁵. Inset: saturated magnetic field ﹩{\left({B}_{\perp }/{B}_{0}\right)}_{\,\rm{sat}\,}﹩ vs. anisotropy parameter ξ for these runs (green pentagon for p⁻⁵, pink square for p⁻⁴, blue nabla for p⁻³). The gray dashed line represents Equation (15).
