Coulomb's inverse-square law, or simply Coulomb's law, is an experimental law [1] of physics that calculates the amount of force between two electrically charged particles at rest.
A visual and tactile classroom model of strong close-range attraction and far-range repulsion characteristic of the fusion potential curve is modeled in the magnetic “Coulomb” barrier apparatus. [3] The apparatus won first place in the 2023 national apparatus competition of the American Academy of Physics Teachers in Sacramento, California.
A Coulombic explosion is a condensed-matter physics process in which a molecule or crystal lattice is destroyed by the Coulombic repulsion between its constituent atoms. Coulombic explosions are a prominent technique in laser-based machining , and appear naturally in certain high-energy reactions.
In analytical electrochemistry, coulometry is the measure of charge transfer during an electrochemical redox reaction. [1] It can be used for precision measurements of charge, but coulometry is mainly used for analytical applications to determine the amount of matter transformed.
The chemical potential μ is, by definition, the energy of adding an extra electron to the fluid. This energy may be decomposed into a kinetic energy T part and the potential energy − eφ part. Since the chemical potential is kept constant, Δ μ = Δ T − e Δ ϕ = 0. {\displaystyle \Delta \mu =\Delta T-e\Delta \phi =0.}
The electromagnetic force, carried by the photon, creates electric and magnetic fields, which are responsible for the attraction between orbital electrons and atomic nuclei which holds atoms together, as well as chemical bonding and electromagnetic waves, including visible light, and forms the basis for electrical technology. Although the ...

Pictorial representation of two interacting charged plates across an electrolyte solution. The distance between the plates is abbreviated by h.. The most popular model to describe the electrical double layer is the Poisson-Boltzmann (PB) model.
