METHODS OF CHARGING A BODY

Making a body to acquire property of attracting small objects is called charging(or electrification). A body can by charged by the following ways:

By rubbing: When a body is rubbed with another body, both of them charged. One of the bodies acquires positive charge and the other acquires negative charge. For example, when a glass rod is rubbed with a silk, the glass rod acquires positive charges, and at the same time, the silk, the silk acquires negative charges.

By conduction: When an uncharged body is made in contact with a charged body flow into the non charged body and the body is charged. For example ,if an uncharged sphere A is made in contact with a charged sphere B, the sphere A will be charged sphere B, the sphere A will be charged with the same charge as in the sphere B.

By induction: When a charged particles or body is brought near non charged body without touching, charges are developed in the uncharged body. This method of charging a body is called charging by induction.
