What is a vector field in a dielectric insulator?
The vector field P describes the polarization (small separation of the charges on each molecule of the dielectric) occurring in a slab of dielectric when it is brought into an electric field. The relative permittivity ε r is greater than one for any insulator; this is due to the polarization of the dielectric which gives an opposing electric field.
