A neutral body is always attracted by the inductor. That's why the trickle of water seems to bend when approaching an electrically charged conductor.

Approaching an inductor with an excess of electrons, the sphere of the electroscope, initially neutral, becomes positive by attraction and the leaves of the electroscope become negatively charged by repulsion.
When touching the sphere, the leaves close. Grounding in the presence of the inductor causes an initially neutral body to acquire a charge of the opposite sign to the inductor. When moving the inductor away, the leaves open because they are positively charged.
The leaf electroscope not only shows whether a body is charged, but also indicates how much it is charged: the greater the amount of charges, the further apart the leaves will be.
Use your electroscope to perform various experiments with electrification.
