From the above electrical field intensity and flux density formulas we can finally derive the following equation, D/E = ε o ε r. It is apparent that the ratio of the electric flux density to the electric field intensity in a point in the field may be understood to be the permittivity of the medium at that point.Definition. The electric displacement field " D " is defined as. where is the vacuum permittivity (also called permittivity of free space), and P is the (macroscopic) density of the permanent and induced electric dipole moments in the material, called the polarization density . The displacement field satisfies Gauss's law in a dielectric: ….

Gauss’s law, either of two statements describing electric and magnetic fluxes.Gauss’s law for electricity states that the electric flux Φ across any closed surface is proportional to the net electric charge q enclosed by the surface; that is, Φ = q/ε 0, where ε 0 is the electric permittivity of free space and has a value of 8.854 × 10 –12 square …Polarization density. In classical electromagnetism, polarization density (or electric polarization, or simply polarization) is the vector field that expresses the volumetric density of permanent or induced electric dipole moments in a dielectric material. When a dielectric is placed in an external electric field, its molecules gain electric ...Hence, units of electric flux are, in the MKS system, newtons per coulomb times meters squared, or N m 2 /C. (Electric flux density is the electric flux per unit area, and is a measure of strength of the normal component of the electric field averaged over the area of integration. Its units are N/C, the same as the electric field in MKS units.)
Here it is: The force applied to a particle bearing charge q q is. F = qv ×B (2.5.1) (2.5.1) F = q v × B. where v v is the velocity of the particle and “ × × ” denotes the cross product. The cross product of two vectors is in a direction perpendicular to each of the two vectors, so the force exerted by the magnetic field is ...
