Not illustrated. 1899 Excerpt: ... to ring an electric bell; but that there is a much less difference of electric pressure between the negative carbon and the third pole. If a continuous current electric arc is formed in the usual way, and if a third insulated carbon, held at right angles to the other two, is placed so that its tip just dips into the arc (see Fig. 62), we can show a similar series of experiments to those described in Lecture II. under the head of the "Edison effect." The arc is rather more under control if we cause it to be projected against the third carbon by means of a magnet. We have now formed on the screen an image of the carbon poles and the arc between them in the usual way. Placing a magnet at the back of the arc, the flame of the arc is deflected laterally and is blown against a third insulated carbon held in it. There are three insulated wires attached respectively to the positive and to the negative carbons of the arc and to the third or insulated carbon, the end of which dips into the flame of the arc projected sideways by the magnet. On starting the arc this third carbon is instantly brought down to the same electrical potential as the negative carbon of the arc, and connecting an amperemeter in between the negative carbon Fig. 62.--Electric Arc projected by magnet against a third carbon, and showing strong electric current flowing through a galvanometer, G, connected between the positive and third carbon. and the third or insulated carbon, we get, as you see, no indication of a current. If, however, we change the connections and insert the circuit of the galvanometer between the positive carbon of the arc and the middle carbon, we find evidence, by the violent impulse given to the galvanometer, that there is a strong current flowing through it.
