PermeabilityImpedancePorous metalsThis paper presents a method, which simultaneously estimates the electrical conductivity and magnetic permeability of porous metals. Porous Cu and Fe manufactured by the lost carbonate sintering process have been tested. An air-cored solenoid coil was designed for the ...
The effective magnetic permeability mu and effective dielectric constant epsilon are two equally important quantities for the characterization of electromagnetic properties of composites. For granular ferromagnetic metals, however, the presence of permanent magnetic moments means that the Maxwell-Garnett theory...

If a material is placed in a magnetic field (H), the magnetic inductance (B), which is a measure of the density of magnetic lines of force within the material, is given by (7.3)B=H+4πM where M is the magnetization of the material per unit volume. The magnetic permeability (µ)...
The structural health monitoring of ferromagnetic materials is essential for controlling product quality. This paper presents the first known characterisation, utilising magnetic induction spectroscopy, of the magnetic permeability of ferromagnetic mater
Substitution of expression for M makes B = μH, where μ = μ0(1 +χ) is the magnetic permeability of matter. The entire information about susceptibility of an object and how it is related to the B, or B0 as it is called in MR imaging, is lumped into μ through χ. Modulation of...
It is not unusual for an optically anisotropic medium, with a permittivity tensor [ϵ], to be characterized by a scalar permeability μ (approximately μ0, the permeability of free space). In this book I use the SI system of units, in which the permittivity and permeability of free space...
During processing of the powders, it is desirable to minimize grain growth so that the sintered powders provide a part with nanocrystalline grain size and high magnetic permeability. The nanosized powder can also be used as a coating, filler or magnetic ink. Due to the small size of the ...
