Aimant d'Aimé, le premier grand instrument pour la science (L')

On the Meudon Bellevue CNRS campus, you will find the first large instrument dedicated to fundamental research in France and in the world, the Large Electromagnet of the Academy of Sciences. It was imagined and designed by the physicist Aimé Cotton in 1928 and operated until the 1970s.
Denis Guthleben, science historian, shares with us the various stages in the history of the large electromagnet, from the birth of the project before the 1914 war to its construction from 1924, with the help of archive images filmed by ONRSI operators. Hubert Pascard, a retired physicist, explains how it works.
