This book contains complete and commented translations of the main works of Charles-Augustin de Coulomb (1736-1806) on torsion, electricity, and magnetism. They include the 1777 prize winning work on the best method of making magnetic needles, the 1784 paper with the law of torsion of metal wires and his 7 major Memoirs on electricity and magnetism. In these works he arrived experimentally at the law of force between electrified bodies varying with the inverse of the square of their distance (known in textbooks as Coulomb's law), at the law of force between magnetic poles also varying with the inverse square of their distance, at the exponential law of charge leakage, at the distribution of electricity over the surface of charged conducting bodies in various configurations of electrostatic equilibrium, at advanced methods of magnetization and the production of artificial magnets.
