Magnetic permeability measurement
WebPermeability (µ) describes the interaction of a material with a magnetic field. A similar analysis can be performed for permeability using an inductor with resistance to represent core losses in a magnetic material (Figure 4). If a DC current source is placed across an inductor, the inductance with the core material can be related to permeability.

WebMagnetic permeability µ is the degree of magnetization of material in response to a magnetic field. It is the ratio of magnetic flux density B and magnetic flux H. The physical constant µ0is the magnetic permeability in vacuum. Relative permeability µris … nothing can hold us down headStandards organizations have recently moved to magnetic constant as the preferred name for μ0, although the older name continues to be listed as a synonym. Historically, the constant μ0 has had different names. In the 1987 IUPAP Red book, for example, this constant was still called permeability of vacuum. Another, now rather rare and obsolete, term is "magnetic permittivity of vacuum". See, for example, Servant et al.
