Relative magnetic permeability

The quantity (1 + /) is called the relative magnetic permeability (also dimensionless), which is also a material property.

Thus, we see the initial connection between optical properties and the electrical and magnetic properties from the two previous sections. Substimtion of Eqs. (6.78) and (6.79) into (6.77) shows that the refractive index can be expressed in terms of the relative electric permittivity (dielectric constant), (cf. Table 6.5), and relative magnetic permeability of the medium, (1 - - x) [cf. Eq. (6.63)], where x is the magnetic susceptibility ... 

The permeability of a magnetic medium /i(ir) is identical to the relative permeability or magnetic constant /ir, and is simply called the permeability. Finally e0(ir) = l/co2 in the emu system. 

The relative magnetic permeability depends on the fiber orientation function, J (see Eq 7.2) ... 

Figure 7.8 shows relationship between the relative magnetic permeability and the fiber orientation function. The results came from an experiment previously discussed (see Figure 7.4). 

Permeability (p) - Magnetic induction divided by magnetic field strength i.e. p = BIH. The relative permeability = q/q, where q is the permeability of a vacuum. [1]... 

Data for some homogeneous metallic materials are given in Table 5.7. Aluminum and steel are the commonly used metallic fillers, and of these, steel provides the most effective EMI-shielding because of its high relative magnetic permeability.

By contrast, if the solenoid has a core made of a soft magnetic material such as a rod of pure iron (e.g., Armco iron) with a relative magnetic permeability of = 1000, the magnetic induction will be greatly improved as follows ... 

For magnetic materials having magnetic losses, the relative magnetic permeability can be written as a complex physical quantity as follows ... 

Therefore, the interdependence between the two dimensionless quantities, i.e., the relative magnetic permeability (p. ) and the magnetic susceptibility ( j of the material, is clearly apparent ...

Non-magnetic materials were measured (relative magnetic permeability ju = 1.0) in the current research. In the future it will be reasonable to study also magnetic aspects of such measurements.
