Question

What is polarisation density?​

Answer 1

In classical electromagnetism, polarization density (or electric polarization, or simply polarization) is the vector field that expresses the density of permanent or induced electric dipole moments in a dielectric material.

hope this will help you..

Answer 2

Answer:

the answer is given below

Explanation:

it is a vector field that expresses the density of permanent or induced electric dipole moments in a dielectric material when a dielectric is placed in an external electric field its molecule can electric dipole moment and the dielectric is said to be polarized the electric dipole moment induced per unit volume of the dielectric material is called the electric polarization of the dielectric

polarization density also describe how material response to an applied electric field as well as the way the material changes the electric field, and can be used to calculate the forces that result from those interactions .
