Define the term - Local electric field and Polarization

Local electric field: It's the sum of the electric field from external sources and field of the dipoles within the specimen.  It's an idealized field measured under certain specified conditions. 

(iv)  Polarization:  Dipole  moment  per  unit  volume  of  the  solid  is  the  sum  of  all  individual  dipole  moments  within  that  volume  and  is known as 'Polarization' P of the solid.
