About Nanohenries per metre
The nanohenry per metre (nH/m) equals 10⁻⁹ H/m. The natural scale for expressing permeability deviations of nearly non-magnetic materials from µ₀ ≈ 1 256.6 nH/m: paramagnetic aluminium (µᵣ = 1.0000220) exceeds µ₀ by about 28 nH/m; diamagnetic copper (µᵣ = 0.999994) falls about 8 nH/m below µ₀. 1 nH/m = 10⁻⁹ H/m.
About Vacuum permeabilities
The vacuum permeability (µ₀), also called the magnetic constant, equals 4π × 10⁻⁷ H/m ≈ 1.25664 µH/m. In the 2019 SI it is experimentally determined: µ₀ = 1.25663706212(19) × 10⁻⁶ H/m. The absolute permeability of any material is µ = µᵣ × µ₀. 1 µ₀ = 4π × 10⁻⁷ H/m.
