How does a non-polar dielectric develop a net dipole moment in an external field?

Asked by Topperlearning User 23rd April 2015, 11:31 AM
Answered by Expert

In the absence of any external field, dipole moment of each non-polar molecule is zero. In the presence of an external field, the centres of positive charges are displaced in the direction of external field while the centres of negative charges are displaced in the opposite direction. This induced dipole in each molecule. The induced dipole moment is added up giving a net dipole moment to the dielectric in the direction of electric field.
