Magnetic permeability definition
Web24 jun. 2015 · Permeability is controlled by such factors as pore size and pore-throat geometry, as well as porosity. To take some account of these factors, the widely used Timur equation [2] relates permeability to irreducible Sw and porosity, and therefore can be applied only in hydrocarbon-bearing zones. WebH c = 155319 A/m * sqrt (BH max /MGOe) So, for example if an N42 magnet were being modeled, the coercivity would be: H c = 155319 A/m * sqrt (42) = 1006582 A/m. For …
