About Picohenries per metre
The picohenry per metre (pH/m) equals 10⁻¹² H/m. Used in calculations for nanoscale magnetic sensors and quantum circuit inductance per unit length. A superconductor in the Meissner state has µ = 0 H/m (B = 0 inside); the full range from 0 to µ₀ spans about 1 256 637 000 pH/m. 1 pH/m = 10⁻¹² 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.
