    Charged Force
Click For Summary
Charge by induction occurs when a charged object, such as a negatively charged plastic rod, is brought near a neutral insulator, causing a redistribution of charges within the neutral object. Although insulators lack free electrons, the charges within their atomic or molecular structure can shift slightly, creating a positive charge at the end closest to the negatively charged rod. This results in two oppositely charged regions forming, which leads to an attractive force between the two objects. The attraction is due to the induced positive charge on the neutral rod, despite its insulating properties. Thus, even insulators can exhibit charge induction, allowing for attraction to occur.

I read that charge by induction precedes force of attraction between a charged body and a neutral one. That is, the nearer end of the body gets oppositely charged when a charged body is brought closer to the neutral one. Since we now have 2 oppositely charged objects (object parts) closely spaced, the force of attraction takes of place. Now my question is about a negatively charged plastic rod brought closer to a neutral plastic rod. The 2 attract each other. How is charge by induction taking place in the neutral rod. The neutral rod, being an insulator does not have free electrons - insulators do not conduct because they do not have free electrons - then, how is positve charge formed on the neutral one at the nearer end to the negatively charged plastic rod?

Charges in insulators cannot roam around freely like in conductors, but they can still shift position slightly on an atomic or molecular scale. This is enough to produce a small net imbalance of charge on a macroscopic scale.
 
Thanks, I should believe it.
