Permeability coefficient คือ

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. WebThe permeability coefficient differs from the diffusion coefficient D by a factor of the partition coefficient u (dimensionless number); i.e., P = UD (2) The partition coefficient u …
