Final answer:
Charging by induction involves redistributing charges between objects without direct contact, leading to charging without physical touch.
Explanation:
Charging by induction is a process in which a charged object is brought near a neutral object, causing a redistribution of charges without direct contact. This method results in the neutral object becoming charged without physical touch.
In the process of induction, the charged object induces opposite charges in the neutral object, leading to attraction and separation of charges, ultimately resulting in the neutral object becoming charged.
One practical example of charging by induction is when a positively charged rod is brought near neutral metal spheres, causing one sphere to become positively charged and the other negatively charged due to the attractive forces.
