Question

Difference between polar and nonpolar dielectrics in physics

Answer 1

NON POLAR DIELECTRICS:

Are made of non-polar molecules.
The center of mass of positive charges coincides with the center of mass of the negative charges, in the molecule.
In its normal state (i.e., in the absence of any external force, esp electric field), each molecule has zero dipole and
has a symmetric shape.
POLAR DIELECTRICS:

Are made of polar molecules.
The center of mass of positive charges does not coincide with the center of mass of the negative charges, in the molecule.
In its normal state (i.e., in the absence of any external force, esp electric field), each molecule has some intrinsic permanent dipole and
has an asymmetric shape.
