About Millihenries per metre
The millihenry per metre (mH/m) equals 10⁻³ H/m ≈ 796 µ₀. The range for soft magnetic materials: grain-oriented silicon steel (CRGO) has µ ≈ 1-10 mH/m at working flux densities (µᵣ ≈ 1 000-8 000); MnZn power ferrites are 3-10 mH/m; nickel-iron alloys (Permalloy 78) reach 25-100 mH/m at low fields. 1 mH/m = 10⁻³ H/m.
About Henries per metre
The henry per metre (H/m) is the SI coherent unit of absolute magnetic permeability, equal to 1 kg·m·s⁻²·A⁻². Only the highest-permeability alloys reach this scale: annealed Mu-metal achieves µ ≈ 0.1-0.4 H/m (µᵣ up to 300 000); Supermalloy under optimal conditions approaches µ ≈ 1 H/m (µᵣ ≈ 10⁶). 1 H/m ≈ 7.96 × 10⁵ µ₀.
