e primary wire consists of 100 yards of No. 12 gauge copper wire (diameter = 264 mm.),its resistance being about a third ofan ohm. The secondary is about10 miles long and has a resistancebetween 6000 and 7000 ohms. Thecoefficient of self-induction of thesecondary is about 450 henrys (967),that of… … from which Idv the binding screw b it enters the primary wire, and havingtraversed this, it emerges by the wire s (fig. 984). Following the directionof the arrows, it will be seen that the current ascends in the pillar z, reachesan oscillating piece of iron, 0, called the hammer^ descends by the…
