erted is said to takeplace by influence or induction. The phenomenon of electrification by induction may bedemonstrated by the following experiment: In fig. 16, let the ebonite rod be electiified by friction and slowly-brought toward the knob of the gold leaf electroscope. The leaves willbe seen to… … Fig. 16.—Experiment to illustrate electrostatic induction. The leaves will diverge, eventhough the charged ebonite rod does not approach to within a foot of the electroscope. is able to produce electrification in that conductor. Thismethod of producing electrification is called electrostatic…
