What is susceptibility tensor?

In general, magnetic susceptibility can be described by a second-order (or rank 2) tensor χ that is referred to as apparent susceptibility tensor in this paper. Specifically, χ is a 3×3 matrix whose elements are denoted as χij. For isotropic susceptibility, this tensor will be diagonal with equal diagonal elements.

What is dielectric tensor?

In response to a magnetic field, some materials can have a dielectric tensor that is complex-Hermitian; this is called a gyro-magnetic or magneto-optic effect. A dielectric tensor that is not Hermitian gives rise to complex eigenvalues, which corresponds to a material with gain or absorption at a particular frequency.

What is susceptibility in dielectrics?

Electric susceptibility, quantitative measure of the extent to which an electric field applied to a dielectric material causes polarization, the slight displacement of positive and negative charge within the material. In both systems the electric susceptibility is always a dimensionless positive number.

What is the difference between susceptibility and permittivity?

As nouns the difference between permittivity and susceptibility. is that permittivity is (physics) a property of a dielectric medium that determines the forces that electric charges placed in the medium exert on each other while susceptibility is the condition of being susceptible; vulnerability.

What is difference between insulator and dielectric?

So, What is the difference between dielectric and insulator? Insulators are materials that do not conduct electricity in an electric field, since they do not have free electrons. On the other hand, dielectrics are insulators that can be polarized.

What are dielectrics give example?

Dielectrics are non-conducting substances. They are the insulating materials and are bad conductors of electric current. Dielectric materials can hold an electrostatic charge while dissipating minimal energy in the form of heat. Examples of dielectric are Mica, Plastics, Glass, Porcelain and Various Metal Oxides.

What is the formula of magnetic susceptibility?

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.
