WebThere are two principal methods by which a dielectric can be polarized: stretching and rotation. Stretching an atom or molecule results in an induced dipole moment added to every atom or molecule. Magnify Rotation occurs only in polar molecules — those with a permanent dipole moment like the water molecule shown in the diagram below. Magnify Web14 apr. 2024 · The dielectric constant ε r (or the static relative permittivity) describes the ability of a material to screen a charge, dampening the strength of its electric field. It is defined as the permittivity of a material divided by the permittivity of free space. The lower the dielectric constant, the less the material will screen an electric field.
