How did Charles-Augustin de Coulomb discover Coulomb’s law?
He suspended a needle with a small plate on one end, and the plate was then charged. Coulomb then measured the period of oscillation at various distances from the large sphere and, using an equation similar to that for the pendulum, related the period to the force between the charges. The result: Coulomb’s law [3].
When did Coulomb contribute to the atomic theory?
Contributions and Achievements: Coulomb issued out his theories in 1785–89. He also developed the inverse square law of attraction and repulsion of unlike and like magnetic poles.
What scientists worked on electricity and magnetism during Coulomb’s time?
French engineer and physicist Charles de Coulomb made pioneering discoveries in electricity and magnetism, and came up with the theory called Coulomb’s Law.
What did Charles Coulomb research?
Coulomb is most famous for his work with electricity and magnetism. His studies and papers were the first thorough accounts of how electricity worked and its relationship to magnetism. In 1777, Coulomb understood that a needle on a pin creates friction and reduces accuracy.
Which is the contribution of Faraday to electromagnetism?
Michael Faraday (22 September 1791 – 25 August 1867) is probably best known for his discovery of electromagnetic induction, his contributions to electrical engineering and electrochemistry or due to the fact that he was responsible for introducing the concept of field in physics to describe electromagnetic interaction.
What is the contribution of Coulomb’s law in electricity?
Coulomb’s law states that in a vacuum, the force between two stationary point charges is inversely proportional to the square of the distance. The power is proportional to the product of the force in the direction in which connected. Charges of the same sign repel, while opposite charge attract.

Who are the scientist that contributed in the development of electromagnetic theory?
About 150 years ago, James Clerk Maxwell, an English scientist, developed a scientific theory to explain electromagnetic waves.
Which of the following technique is named after Charles-Augustin de Coulomb?
… had obtained some remarkable results by using the torsion balance method: law of attraction and repulsion, the electric point charges, magnetic poles, distribution of electricity on the surface of charged bodies and others.
