  • Born-Oppenheimer approximation [r]: A technique in quantum mechanics in which the kinetic energies of nuclei and electrons are calculated separately. [e]
  • Clausius-Mossotti relation [r]: connects the relative permittivity εr of a dielectric to the polarizability α of the atoms or molecules constituting the dielectric. [e]
  • Coulomb's law [r]: An inverse-square distance law, like Newton's gravitational law, describing the forces acting between electric point charges; also valid for the force between magnetic poles. [e]
  • Electric displacement [r]: a vector field D in a dielectric; D is proportional to the outer electric field E. [e]
  • Electric field [r]: force acting on an electric charge—a vector field. [e]
  • Electricity [r]: The flow or presence of electric charge; the flow of electricity is an important carrier of energy. [e]
  • Electromagnetic wave [r]: A change, periodic in space and time, of an electric field E(r,t) and a magnetic field B(r,t); a stream of electromagnetic waves, referred to as electromagnetic radiation, can be seen as a stream of massless elementary particles, named photons. [e]
  • Farad [r]: SI unit of capacitance; symbol F: 1 F = 1 C/V [e]
  • Gauss' law (electrostatics) [r]: Relates the surface integral of the electric displacement through a closed surface to the electric charge enveloped by the closed surface. [e]
  • Gauss' law (magnetism) [r]: States that the total magnetic flux through a closed surface is zero; this means that magnetic monopoles do not exist. [e]
  • Gaussian units [r]: A centimeter-gram-second system of units often used in electrodynamics and special relativity. [e]
  • Green's function [r]: Auxiliary function in the theory of linear differential equations; integral operator with Green function as kernel is the inverse of a linear differential operator. [e]
  • Lorentz-Lorenz relation [r]: An equation describing the relation between the density and index of refraction of a dielectric. [e]
  • Magnetic constant [r]: A physical constant in the International System of Units (SI) relating mechanical force and electric current in classical vacuum with a defined value μ0 = 4π × 10−7 N/A2. [e]
  • Maxwell equations [r]: Mathematical equations describing the interrelationship between electric and magnetic fields; dependence of the fields on electric charge- and current- densities. [e]
  • Momentum [r]: mass of a particle times its velocity (a vector). [e]
  • Polarizability [r]: The ease by which a charge-distribution polarizes; describes the amount of charge separation caused by an electric field. [e]
  • Relative permittivity [r]: A factor describing the polarizability of a material or medium as a proportionality between an electric displacement and an electric field in a dielectric. [e]
  • Speed of light [r]: A physical constant c describing the speed of electromagnetic radiation in vacuum. In the International System of Units the metre is the distance light travels in classical vacuum in 1/c seconds, using the defined value c = c0299  792  458 m/s (exact). [e]
  • Statcoulomb [r]: Unit of electric charge in cgs-esu units: 1 statC = C/(10⋅c), with c the speed of light in m/s. [e]
