WebPermeability is the ability to support formation of magnetic fields in a material. Permeability is measured in H/m (henries/m) or newtons/ampere 2 (N/A 2).. The Permeability of Free Space. The permeability of free space µ 0 (the permeability constant or the magnetic constant) is. µ 0 = 4π 10-7 (H/m) . ≈ 1.257 10-6 (H/m, N/A 2). The Relative Permeability Webis that permeability is a quantitative measure of the degree of magnetization of a material in the presence of an applied magnetic field (measured in newtons per ampere squared in SI …
