## Electrification Experiments

Electrification (charging ) represents a phenomenon of charge transfer. There are three types of electrification of an object by:

- Friction

- Conduction

- Influence

### Electrification by Friction

We rub a plastic or glass ruler with wool and bring it close to the small pieces of paper, it attracts it. Without friction nothing happens, after friction the ruler will be electrified (charged). We say that there is a mechanical removal of electrons from a body

### Electrification by Conduction

Contact electrification occurs on a neutral object when a charged object is in contact with it.

During conduction the same charge is created in a neutral object. Electrons will transfer from a negative object to a neutral object making it negative.

Charging By Conduction Facts :

- Contact

- Same charge

- Permanent (with electron transfer)

### ELECTRIFICATION BY INDUCTION ( INFLUENCE )

You can induce a charge in a neutral object by moving a charged object close to it.

Induction electrification or influence creates a temporary and opposite charge in that other object with no contact.

This is considered temporary because no electrons are transferred and neutrality returns when the close charged object is removed.

Charging By Induction Facts

- No contact

- Opposite charge

- Temporary (no electron transfer)
