CONT

Edouard Branly [is a] French physicist and inventor of the coheror employed in wireless telegraphy...

CONT

It consists in a glass tube filled with metal filings which acts as an insulator when placed in a circuit comprising a battery and a galvanometer. However, if an electric spark is created some distance away, it becomes a conductor and lets the current pass into the circuit. When the tube is tapped lightly it becomes an insulator again and interrupts the current.

CONT

Next to the rock, the boy held a two and a half meter long pole, along which ran a metallic wire, probably connected to a Branly coherer, a battery, and a bell.

Domaine(s)

CONT

Il s'agissait, à l'origine, d'un simple «petit tube de verre qui ressemblait à un thermomètre» mais qui était rempli de limaille de fer. Branly découvrit que les ondes électro-magnétiques pouvaient provoquer à distance la cohésion des particules de limaille contenues dans le cohéreur, ce qui permettait à un courant électrique de la traverser.
