Permeability nitrogen

WebPermeability is the ability to support formation of magnetic fields in a material. Permeability is measured in H/m (henries/m) or newtons/ampere2 (N/A2). The Permeability of Free Space The permeability of free space µ0 (the permeability constant or the magnetic constant) is µ0 = 4π 10-7 (H/m) ≈ 1.257 10-6 (H/m, N/A2) The Relative Permeability http://en.labthink.com/en-us/literatures/detailed-introduction-to-material-permeability-indexes.html

In electromagnetism, permeability is the measure of magnetization that a material obtains in response to an applied magnetic field. Permeability is typically represented by the (italicized) Greek letter μ. The term was coined by William Thomson, 1st Baron Kelvin in 1872, and used alongside permittivity by Oliver Heaviside in 1885. The reciprocal of permeability is magnetic reluctivity.
