Explain concept of charging by induction.

Answer»

1. If an uncharged conductor is brought near a charged body, (not in physical contact) the nearer side of the conductor develops opposite charge to that on the charged body and the far side of the conductor develops charge similar to that on the charged body. This is called induction. 

2. This happens because the electrons in a conductor are free and can move easily in presence of charged body. 

3. A charged body attracts or repels electrons in a conductor depending on whether the charge on the body is positive or negative respectively. 

4. Positive and negative charges are redistributed and are accumulated at the ends of the conductor near and away from the charged body. 

5. In induction, there is no transfer of charges between the charged body and the conductor. So when the charged body is moved away from the conductor, the charges in the conductor are free again.
