TYPES OF POLARIZATION -- IONIC POLARIZATION
There are four types of Polarization like Electronic Polarization, Ionic Polarization, Orientation Polarization and Space Charge Polarization. The displacement of charge and formation of dipole in dielectric material when placed in an external field is called Polarization.
Ionic Polarization results from the separation of +ve and --ve ion air molecule held together by ionic bonds. When an electric field is applied to such a molecule their positive and negative ion are displaces further in opposite direction and their inter ionic separation increases until bonding force to stop the process and thus increasing the dipole moment. This is called Ionic Polarization.
