Bulk Lorentz factor (left) and the magnetic field distribution (right) in pulsar wind with distance from the light-cylinder radius r_LC for the MR and PL magnetization decay models with different spin period of P_spin = 2.5 ms and 14.25 ms. The dotted line indicates the position of the IBS nose, i.e., the shock stand-off distance (l₀). In the left panel, the horizontal dotted line depicts the maximum Lorentz factor Γ_max, corresponding to complete conversion of the available Poynting flux into bulk kinetic energy. In the right panel, the toroidal field model (B ∝ l⁻¹) is compared with the MHD-compressed field derived from shock jump conditions.
