What is the difference between the two and what are the applications of them in a magnetic material?
Magnetic susceptibility and relative permeability are both measures of the response of a material to an applied magnetic field. However, magnetic susceptibility is a dimensionless quantity that describes the degree to which a material can be magnetized, while relative permeability is a ratio that compares the material's permeability to that of a vacuum.
Magnetic susceptibility and relative permeability are related through the equation χ = μr - 1, where χ represents magnetic susceptibility and μr represents relative permeability. This means that magnetic susceptibility is directly proportional to relative permeability.
Magnetic susceptibility and relative permeability are important properties of materials that determine their response to magnetic fields. Materials with high magnetic susceptibility and relative permeability are easily magnetized and can enhance the strength of a magnetic field, while materials with low values are less affected by magnetic fields.
Magnetic susceptibility and relative permeability can be measured using various techniques, such as vibrating sample magnetometry, magnetic balance, or through calculations based on magnetic field strength and induced magnetic moment in the material. The units for both properties are dimensionless.
The values of magnetic susceptibility and relative permeability are influenced by factors such as the composition, structure, and temperature of the material. In addition, the presence of impurities or magnetic domains within the material can also affect these properties.
