A few sample values are given in Table. 2. Table 2: Magnetic Susceptibility and Permeability. is known as the magnetic susceptibility. If $ \chi_m$ is positive then the In fact, from Equation (689), we can write Magnetic susceptibility is monitored on discrete samples during thermal demagnetization experiments to recognize changes in the magnetic mineralogy caused by where χ is the paramagnetic susceptibility, Ig is the intensity of magnetization, Hg is the applied magnetic field, M is the molecular weight of the sample under calculate the magnetic susceptibility of the Ag atom to within 10% accuracy, the published and in the presence of paramagnetic complexes using Equation 5. Magnetic susceptibility χm = Km - 1. For paramagnetic and diamagnetic materials the relative permeability is very close to 1 and the magnetic susceptibility very In diamagnetic materials the magnetic susceptibility is negative.

Magnetic susceptibility, is denoted by the Greek letter chi (χ), is defined as the magnitude of the internal polarization (J) divided by the strength of the external field (B o): χ = J / B o Since it is the ratio of two magnetic fields, susceptibility is a dimensionless number.

For paramagnetic and diamagnetic materials the relative permeability is very close to 1 and the magnetic susceptibility very
In diamagnetic materials the magnetic susceptibility is negative.

### Before defining the term magnetic susceptibility, we need to know some terms such as magnetic field (H), magnetic flux density (B) and magnetic permeability (µ) Magnetic field : Lines of force will be produced which diffuses through the medium where the field is applied.

Thus the volume magnetic susceptibility χ v and the magnetic permeability μ are related by the following formula: μ = μ 0 ( 1 + χ v ) . {\displaystyle \mu =\mu _{0}\left(1+\chi _{\text{v}}\right).} Magnetic Susceptibility Formula χ: magnetic susceptibility M: magnetization H: field intensity The magnetic susceptibility measures the strength of interaction on placing the substance in a magnetic field. For chemical applications the molar magnetic susceptibility (χ m o l) is the preferred quantity and is measured in m 3 ·mol −1 (SI) or cm 3 ·mol −1 (CGS) and is defined as (20.10.1) χ mol = M χ v / ρ Magnetic Susceptibility The magnetic susceptibility measures the strength of interaction on placing the substance in a magnetic field. For chemical applications the molar magnetic susceptibility (χmol) is the preferred quantity and is measured in m 3 ·mol −1 (SI) or cm 3 ·mol −1 (CGS) and is defined as χmol = Mχv / ρ 2021-04-14 · The magnetic susceptibility of a material, commonly symbolized by χm, is equal to the ratio of the magnetization M within the material to the applied magnetic field strength H, or χm = M / H. The Johnson-Matthey magnetic susceptibility balance is very similar to the traditional Gouy balance but, instead of measuring the force that a magnet exerts on a sample, the opposite force that the sample exerts on a suspended permanent magnet is observed. The mass susceptibility, χg, is calculated using: χg ClR Rbal o m = ()− 109 where: l = sample length (cm) 2020-10-28 · Magnetic permeability : It denotes the relation between the magnetic field and magnetic flux density.
