About Microhenries per metre
The microhenry per metre (µH/m) equals 10⁻⁶ H/m. The most practical scale for absolute permeability: vacuum permeability µ₀ ≈ 1.257 µH/m, so all non-magnetic materials (air, plastics, biological tissue) have µ between 1.256 and 1.258 µH/m. Relative permeability is simply µᵣ = µ / 1.257 µH/m. 1 µH/m = 10⁻⁶ H/m.
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.
