Magnetic core .However,iron has a relative permeability of 5,000 when it is 99.8 percent pure,and the relative permeability of soft iron with 99.95 percent purity is a massive 200,000.This huge relative permeability is why iron is the best core for an electromagnet.results for this questionWhat is the permeability of concrete?What is the permeability of concrete?Fig.1 explains the relationship between water to cement ratio and concrete permeability.Typically,at a water cement ratio of around 0.4,permeability is practically nil.Finally,superplasticizer with mixture allows the use of low water to cement ratio,so concrete with low permeability can be produced with the use of superplasticizer.Permeability of Concrete and Factors Influencing Itresults for this questionWhat is permeability of oil?What is permeability of oil?This is normalized relative permeability.Normalized relative permeability defines the oil relative permeability at the critical water saturation (water becomes mobile) as a value of one (1.0),and defines the absolute permeability as the effective at the critical water saturation.Relative Permeability - IHS
