The current,thus established, gives polarity to the faces of thearch,… … THERMO-ELECTRIC ROTATIONS. 125 south pole, similar poles are presented towards eachother, and the arch is obliged to make a semi-revolu-tion on its axis, in order to present its northern faceto this pole. This movement brings the other junc-tion into the flame, and a current is produced oppositeto…
