Proposed Method of Permeability Measurement The objectives of the proposed method are; (1) simple measurement of single thin magnetic sheets, (2) determination of the real part and the imaginary part of the relative … WebFeb 6, 2024 · The permeability is a measure of the ease with which liquids and gases can pass through a rock. The more consolidated the material, the lower its permeability. Thus "loose" materials like gravel have high permeability. Some rocks can also have anisotropic permeability, meaning that fluids can flow easily in one direction, but not in another. 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. hawkswood school employment
