Charles-Augustin de Coulomb (1736–1806) was a French physicist and civil engineer best known for his work in electrostatics and magnetism. He is most famous for formulating Coulomb's Law, which describes the force between two charged objects. This law states that the electric force between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.
