induction
When a neutral object is brought close to a positively charged object, the positive object induces a separation of charges within the neutral object, causing the side closer to the positive object to become negatively charged. This attraction between the positively charged object and the induced negative charges on the neutral object results in an overall attractive force between the two objects.
A neutral substance acquires opposite charge to the object brought near it. For example, if a negatively charged object is brought close to a neutral substance, it will induce a positive charge on the neutral substance through the process of electrostatic induction.
Inducing a charge by bringing a neutral object close to a charged object is called electrostatic induction. This process causes the redistribution of charges within the neutral object, resulting in the neutral object acquiring a charge.
If the event horizon (space, in this case) of one of the items is breeched by the other and touch, the neutral object becomes negatively charged. If they never touch, they both remain in their present condition. The neutral object's condition will never affect the charge of the negatively charged object, whether they touch or do not touch. The negatively charged item's condition will never change, regardless of physical touch between the two items. ***************Contributed by Czar Acumen*******************
Charging a neutral object by bringing it close to a charged object is known as charging by induction. When a charged object is brought near a neutral object, the charges in the neutral object are rearranged, causing one side to become oppositely charged to the charged object, resulting in an overall charge on the neutral object.
Bringing a neutral object close to a charged object is known as induction. This process can cause the neutral object to become charged temporarily through the redistribution of charges.
None. That said, most neutral objects we meet in everyday life are composed of positively and negatively charged objects which simply cancel out to give an overall neutral object. This is important because they can create Van der Waal forces, since the positive is a bit stronger than the negative in some areas very close to the object, and vice versa.
induction
To leave an object positively charged using the induction method, start by bringing a negatively charged object close to the neutral object. This induces a temporary separation of charges, with negative charges moving to the farther side of the neutral object. Then, while the negatively charged object is still nearby, remove it, leaving the neutral object with an excess of positive charges, thereby leaving it positively charged.
Adding an oppositely charged atom/molecule which usually creates an ionic bond, though in certain cases it can form a covalent bond. Or you can oxidize or reduce the species through chemical reactions or physical bombardment with electrons or protons.
When a charged object is brought close to a neutral object, the electric field from the charged object can cause the electrons in the neutral object to be attracted or repelled. This movement of electrons results in the neutral object becoming polarized, as the electrons are pushed away from or pulled towards the charged object.
