Orientation polarization

This is also called dipole polarization and consists in the aligning of the axes of permanent dipoles along the direction of the intensity vector of the field. As a result of combined action of the electric field and thermal agitation of molecules which disorients the dipole molecules, preferred orientation of the dipole molecules occurs in alignment with the field. Orientation polarization increases with the intensity of the field and decreases with a rise in temperature. It is found in many liquids and gases.
