Question

4. Material possess electrical polarization in which absence of an applied field and owing
to their structure, possess
b) temporary dipole moment
a) permanent dipole moment
c) permanent magnetic
d) temporary magnet​

Answer 1

Answer:

A material is said to be polarized if the positive and negative charges within the material become slightly displaced from one another due to an electric field. ... The net result is that some charge accumulates on the surface of the material.

Answer 2

A.  Material possess electrical polarization in which absence of an applied field and owing to their structure, possess permanent dipole moment.

Permanent dipole moment:

Permanent electric dipole moment of any particle is the charge separation along the direction of the total angular momentum of the system and also tends to arise from elementary particle moments which directly violate parity and the symmetry of time-reversal.

Therefore, material possess electrical polarization in which absence of an applied field and owing to their structure, possess permanent dipole moment.
