The communication was thus established between the two poles; the current, starting from the positive pole, traversed the wire, passed through the magnet which was temporarily magnetized, and returned through the earth to the negative pole.
Si la comunicación se establecía entre los dos polos, la corriente, partiendo del polo positivo, atravesaba el alambre, pasaba al electroimán, que se imantaba temporalmente, y volvía por el suelo al polo negativo.
