			Coulomb leaves a legacy as a pioneer in geotechnical engineering for his contribution to retaining wall design.

			Charles de Coulomb's name is one of the 72 names inscribed on the Eiffel Tower.

			Coulomb explained the laws of attraction and repulsion between magnetic poles and electric charges, but he did not find any relationship between the two. He believed that the attraction and repulsion were brought on by different kinds of fluids.

			Coulomb worked strenuously on friction of machinery, windmills, and the elasticity of metal and silk.

Coulomb’s Law

	Coloumb used a torsion balance to examine repulsion and attraction forces of charged particles. This torsion balance he used includes an insulating rod with a metal-coated ball attached to an end suspended from the middle of it by a silk thread. After charging the ball with static electricity, a second charged ball would be brought near it. The two balls repelled one another. Through much analysis, he discovered that the magnitude of the electric force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges. The force is along the straight path between them, and if the charge of the two particles have the same sign then the force is repulsive while if they have different signs the force is attractive.
