Magnetic Susceptibility Formula, Calculator, X Calculation

Magnetic Susceptibility:

Magnetic susceptibility is a numerical measure of the ability of a material to become magnetized in response to a specific applied magnetic field.

Mathematically, the ratio of the magnetization M within the material to the applied magnetic field strength H is called the magnetic susceptibility of the material. Magnetization involves a certain amount of magnetic dipole moment per unit volume, and this ratio is technically called volume susceptibility.

The degree of magnetization of a material in response to an applied magnetic field is measured by magnetic susceptibility. It is a dimensionless proportionality constant. Susceptibility refers to the overall amount of magnetization that occurs at the same instant a magnetic field is applied to an object.

  • Interactions between electrons and nuclei cause this phenomenon.
  • Sensitization arises when both nuclei and electrons are applied externally under a magnetic field.

Magnetic Susceptibility Formula:

Magnetic susceptibility X(A/m) in Ampere per meter is equal to the magnetization M(A) in Ampere and divided by the field intensity H(T) in Tesla. Hence the Magnetic susceptibility formula can be written as
