An electrical dipole is formed when positive and negative charges are separated by a small distance.
In dielectric materials, when an electric field is applied, charges may shift slightly from their equilibrium positions.
This produces dipoles inside the material.
The formation or alignment of electric dipoles in a dielectric material is called polarization.
Polarization is very important in dielectric materials and capacitors.
Polymerization is the formation of polymers from monomers.
Magnetization is related to magnetic dipoles.
Semiconducting refers to electrical conductivity behavior.
Therefore, the formation of electrical dipole is called:
