Webb1 juni 2024 · P. Beckley, in Encyclopedia of Materials: Science and Technology, 2001 2 Stimulus-response. Soft magnetic materials may be described by a stimulus-response pattern. When stimulus—a magnetizing force H in amperes per meter—is applied it leads to a response in the form of magnetization B in teslas. The ratio of these is descriptive of … WebbThe permeability of a material is determined by assessing how much a material resists the flow of fluids—if it takes a lot of pressure to squeeze fluid through the material it has low permeability. Conversely, if the fluid travels through easily it has high permeability. What Is Good Permeability?
In electromagnetism, permeability is the measure of magnetization that a material obtains in response to an applied magnetic field. Permeability is typically represented by the (italicized) Greek letter μ. The term was coined by William Thomson, 1st Baron Kelvin in 1872, and used alongside permittivity by Oliver Heaviside in 1885. The reciprocal of permeability is magnetic reluctivity. Webb16 feb. 2024 · Influence of the material porosity. The porosity of a material is decisive when evaluating its durability and resistance to adverse conditions. The distribution of pores and their characteristics defines the permeability of the material, that is, its ability to store fluids, thus conditioning its physical and chemical properties..
