Permeability (electromagnetism) - Wikipedia
In electromagnetism, permeability is the measure of magnetization produced in a material in response to an applied magnetic field. Permeability is typically represented by the (italicized) Greek letter μ. It is the ratio of the magnetic induction to the magnetizing field in a material.
Permeability (materials science) - Wikipedia
In fluid mechanics, materials science and Earth sciences, permeability (commonly symbolized as k) is a measure of the ability of a porous material (often, a rock or an unconsolidated material) to allow fluids to pass through it.

Permeability - The Engineering ToolBox
Permeability 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 µ0 (the permeability constant or the magnetic constant) is. µ0 = 4π 10 -7 (H/m) ≈ 1.257 10-6 (H/m, N/A2)
