The electroscope can also be charged without touching it to a charged object, by electrostatic induction. If a charged object is brought near the electroscope terminal, the leaves also diverge, because the electric field of the object causes charges in the electroscope rod to separate the leaves. Charges of the opposite polarity to the charged ...
