Web25. jan 2024 · Sediment permeability also plays an important role in governing the evolution of pore fluid pressure along the plate boundary given its control on the rate of fluid drainage. Within subduction zones, fault zones in the upper plate are important pathways for fluid flow and enhance drainage of the plate boundary as they often exhibit higher ... 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
