WebNov 3, 2016 · The permeability and permittivity of free space, μ 0 and ϵ 0, are not the same. This you can already see by their different units F / m and N / A 2, respectively. However, in the SI system, they are related by the speed of light c 0 via ϵ 0 μ 0 = 1 c 0 2 The value of μ 0 = 4 π 10 − 7 N / A 2 is assumed. WebDec 14, 2024 · Permittivity is defined as the flow rate (in cubic metres per second), divided by the area of the geotextile tested, divided by the hydraulic head. ASTM D4491 specifies a hydraulic head of 50mm for testing. Figure 1: General arrangement for measuring water flow through a geotextile Comparison

WebMay 3, 2016 · Permittivity and permeability are two different measures used in electromagnetism. Permittivity measures the ability of a material to store energy within the material. Permeability, on the other hand, is a measure of the ability of a material to support the formation of a magnetic field within the material.
