Volume susceptibility M is the magnetization of the material (the magnetic dipole moment per unit volume), with unit amperes per meter, and H is the magnetic field strength, also with the unit amperes per meter. Se hela listan på chemeurope.com When a material is placed in a magnetic field H, a magnetization (magnetic moment per unit volume) M is induced in the material which is related to H by M = κH, where κ is called the volume susceptibility. Since H and M have the same dimensions, κ is dimensionless. A more useful parameter is the molar susceptibility χ m, defined by χ m = κV m = κ M/ρ 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 (Bo): χ = J / B o Since it is the ratio of two magnetic fields, susceptibility is a dimensionless number. Both oersted and gauss are expressed as cm-1/2 ּg 1/2 ּs-1 in terms of base units. f. A/m was often expressed as “ampere-turn per meter” when used for magnetic field strength.
The designation “emu” is not a unit. i. Recognized under SI, even though based on the defition B = μ o H + J. See footnote c. j magnetic dipole moment 1 erg/G = 1 emu → 4π × 10−10 Wb·m J magnetic polarization 1 erg/(G·cm 3 ) = 1 emu/cm 3 → 4π × 10 −4 T χ, κ susceptibility 1 → 4π !The molar magnetic susceptibility , PM, is obtained from the mass magnetic susceptibility by multiplying by the molecular weight of the sample in units of g/mol; i.e., Although susceptibility is dimensionless, it differs by a factor of 4between the two systems. The defining equations above require Earth magnetic field values to be given in oersted (cgs) or A/m (SI).
