Explain electric polarization.

Electric polarization: This polarization density is the vector field such expresses the density of permanent or induced electric dipole moments into a dielectric material. This SI unit of measure is coulombs per square metre.

The electric polarization P is explained as the difference among the electric fields D (induced) and E (imposed) in a dielectric because ofbound and free charges, correspondingly. In cgs, p = (D - E)/ (4π) that can be written in terms of the electric susceptibility (χe) as P = χeE

In MKS, P =∈0 χe E, here ∈0 is the permittivity of free space.
