Electric field line Electric field lines are a visual representation of the electric field around an electric charge. In the case of a point charge, it can be expressed in spreading around the charge. The denser the electric field line,…

What happens when the charged body is close to the conductor and insulator?

Conductor
Electrostatic induction is a redistribution of electrical charge in an object caused by nearby charges' influence. In the presence of a charged body, an insulated conductor develops opposite charges on the near end and the same charges on the other end.

Insulator
When a charged body is brought near a neutral substance, the distribution of charge in atoms and molecules is shifted slightly. An opposite charge is attracted nearer the charged rod, while the same charge is pushed.

The structure of the water molecule

Water is a representative 'polar molecule'. The hydrogen-oxygen-hydrogen bonds that make up the water molecule have an angle of 104.5˚ and appear curved. Because of this unbalanced water molecule structure, the oxygen side has (-) electricity, and the hydrogen side has (+) electricity.

Electroscope

Using an electroscope, you can determine whether an object is charged or the polarity of the charge.

When the (+) charged body is close to the metal plate, the metal foil's free electrons are attracted to the metal plate, and a positive charge is induced in the metal foil. The electric force unfolds metal foil.
In addition, when the (-) charged body is brought close to the metal plate, free electrons of the metal plate are pushed out, and negative charges are induced in the metal foil. As before, the metal foil is unfolded by the electric force.
In other words, when the electroscope is electrically neutral, the metal foil will unfold when a positive or negative electric charge comes close to it.

Check the polarity of the charged body using an electroscope

Using an electroscope, you can check the polarity of an electric charge. For example, let's assume an electroscope in which a metal foil is opened with a negative charge.
If you bring the (+) charged body close to this electroscope, the metal foil will shrink.
On the other hand, if you get closer to the (-) charged body, the metal foil will unfold more.
