Charging by Induction deals with charging a material without actually keeping it in contact with another charged material. This approach is used where the charged object is placed near an uncharged conductive object, grounded on a charged material that is neutral in nature. The charge flows between two materials, and the uncharged conductive object receives the charge with opposite polarity. Charging by Friction deals with rubbing one object on another, causing the electrons to move from one area to another. This approach is helpful for Charging insulators.

As a result, the negatively charged element electrons from sphere A get transmitted to sphere B. The transfer of electrons makes sphere A become positively charged, and the sphere acquires a negative charge.
The overall two-sphere system becomes electrically neutral in nature. The spheres are then separated with the help of an insulating cover such as gloves. However, remember to avoid direct contact with the metal. When we remove the balloon, the charge gets retransmitted, scattering throughout the spheres.
Subsequently, sphere A is negatively charged, and sphere B is positively charged. The spheres are then detached with the help of an insulating cover such as gloves. When the balloon is eliminated, the charge gets redistributed in spheres A and B, scattering out evenly.
The explanation of the process of charging by induction is frequently done within an electroscope. In this explanation, a charged object is placed close to the electroscope but not touching it. The negatively charged element in the electroscope is enticed to make movement due to the presence of the charged object above the plate of the instrument.
Basic Principles from Charging Of Electroscope by Induction
The charged object placed on the plate is touched with the electroscope. Here, the electrons make movement between the electroscope and the ground allowing the electroscope to attain an overall charge.
The needle of the electroscope turns aside, depicting an overall charge when the charged object is repelled. From this explanation, we can summarise the following basic principles-
- The element being charged by induction never touches the charged object.
- The Charged element does not transmit negatively charged elements or attain them from the element being charged.
- The element being charged stay in contact with the ground. Negatively charged elements are transmitted between the ground and the object being charged.
- The charged elements serve to polarize the element being charged.
- The element being charged eventually attain a charge that is contrary to that of the charged element used to polarise it.
The most well-known application is the charging of electric vehicles, where automatic and wireless inductive charging is provided as a substitute for plug-in charging.
