WebApr 9, 2024 · Also known as electromagnetism, magnetic permeability is the measure of a material’s resistance against the formation of a magnetic field. It can be defined as a relative increase or decrease in the resultant magnetic field (M.F.) inside any material as compared to the magnetizing field in which the given material is located. WebThe permeability coefficient is the product of gas flux and membrane thickness divided by the pressure difference across the membrane. Gas selectivity is the ratio of permeability coefficients of two gases (R A/B) P A/P B), where P A is the permeability of the more permeable gas and P B is the permeability of the less permeable gas in the ...
