Who Discovered Coulomb's Law and the Concept of Electric Field Lines?

AI Thread Summary
Coulomb's Law was discovered by Charles-Augustin de Coulomb and published in 1785 in the History of the Royal Academy of Sciences in France. The concept of electric field lines was later developed, with Michael Faraday being credited for applying the idea of field lines to electric fields, similar to his work with magnetic fields. The discussion highlights the need for reliable sources to reference these historical developments. Participants are encouraged to share additional information regarding the timeline and contributors to the concept of electric field lines. The inquiry reflects a broader interest in the historical context of electrical theory.

Does anyone know when Coulomb discovered his law? And does anyone know when the concept of electric field lines was invented? I know that Faraday created the idea for the magnetic field and I was wondering if it was he who applied it to the electric field or was it someone else?

Sources of information will be appreciated since I will eventually have to refer to the source of information.

Thank you

Pete

Well I found the Coulomb part. His experiment was published in

Charles A. de Coulomb, History Royal Acad. Sci. (France), 1785, pp. 569 and 579.

The rest I'm still searching for. Thanks.

It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
