How Does Coulomb Use Electricity And Magnetism?

Electricity and magnetism are two different aspects of one force. This force is called the electromagnetic force. Electricity can be generated by rotating coils of wire in the vicinity of a magnet. When a force moves objects toward and away from each other it is called electricity. When it comes to magnets, Earth and other planets behave like giant magnets. The first know magnets were iron materials. If one piece of the iron was placed in contact with the other, it attracted it. In ancient times men knew of a special kind of rock that could pull other rocks of the same kind and pieces of iron toward itself. Such rocks were called lodestones. In modern times man uses the same force exerted by the ancient lodestones to generate electric power, to store information in computers, and to study the secrets of the universe. The force is called magnetism, and objects that exert it are known as
Charles Augustin de Coulomb completed a many experiments in which he passed different amounts of electrical charge onto objects and then measured the force between them. He also studied frictional forces. In 1779, he published an important investigation of the laws of friction. In 1785, Coulomb presented his three reports on Electricity and Magnetism, In these reports he described how to construct and use an electric balance, determination of how magnetic and the electric fluids act, and the quantity of Electricity. He used the scientific method to observe and testing these experiments repeatedly. He concluded that the electrical force was in some ways very similar to the gravitational force that Issac Newton had discovered many years earlier. Using the scientific method, he observed that if two electrically charged objects are moved farther away from each other, the force between them gets smaller, just like gravity. Coulomb summarized his finding in a simple relationship know as the Coulomb
