Final answer:
Charging by induction is a process of charging an object without contact. It involves polarizing a neutral object using a charged rod and then grounding the object to allow excess charge to be attracted or repelled, resulting in an opposite charge to that of the rod.
Step-by-step explanation:
Charging by induction is a process of charging an object without contact. It involves polarizing a neutral object using a charged rod and then grounding the object to allow excess charge to be attracted or repelled, resulting in an opposite charge to that of the rod. Charging by induction is a method of charging an object without direct contact by creating a charge in a nearby object.
In this process, a neutral object is polarized when a charged rod is brought near it. The object is then grounded, meaning that a conducting wire is connected from the object to the ground. Excess charge is attracted to or repelled from the object through the ground wire, leaving the object with an opposite charge to that of the rod.
