Electric polarization

Polarization occurs when an electric field distorts the negative cloud of electrons around positive atomic nuclei in a direction opposite the field. In classical electromagnetism, polarization density is the 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 fiel its molecules gain electric dipole moment and the dielectric is said to be polarized.

Meaning, pronunciation, translations and examples. The electric polarization P is defined as the difference between the electric fields D (induced) and E (imposed) in a dielectric due to bound and free charges, respectively. In an earlier section of Lesson it was stated that an electrical attraction would be observed between a charged object and a neutral object.

If a charged plastic tube is held near to neutral paper bits, the attraction between the paper and the plastic would be sufficient to raise the paper off the table. If there are $N$ such molecules per unit volume then the electric polarization. Electric polarization is the extent to which polar molecules have been induced in a dielectric.
