# Why does the comb attract the pieces of papers if they're neutral?

When we rub our hairs with a comb, and then try to attract small pieces of paper, they're attracted by the comb. The pieces of the paper were not electrified before they were attracted. Then they might be neutral. Why does the comb attract the pieces of the paper if they're neutral, and have no influence of a specific charge on them (Pieces of paper).

This is because the neutrality of polarity can be changed by electric field in this case. When you create - charge in the comb and you expose the pieces of paper to the electric field created by the charge, you will polarise them so that the part closer to the comb will be + and the other will be -.

Here, see the electric field. The same polarities do not like each other:

This does not answer the most important thing -- why are there more negative charges in the comb in the first place? – Pricklebush Tickletush May 7 '13 at 0:11
Unfortunately, this question is not being asked by the OP. – Tomáš Zato May 8 '13 at 13:45
You have same comb as I. :) – user66452 Dec 6 '15 at 19:55

Basically, when an electrification takes place, electrons are not created but they are transferred..... in the case of comb attracting tiny tiny bits of papers when rubbed with dry hair is because electrons from the dry hair gets transferred to the comb and now the comb induces a dipole in the bitties of paper and the paper gets attracted...

-

Due to the induced dipole they get attracted to the electrified comb i.e, negative charge.

-

As the hair have negative charge it get attracted to the positive charge of the comb. When we take comb to the bits of paper then it get induced

Hi user57145, this is a pretty incomplete answer. Can you expand this to explain better? – Brandon Enright Aug 12 '14 at 14:40

when we comb our hair our comb get charged and when we bring comb near pieces of paper the charge get induced on paper.[induced means when we bring any charged partical towards neutral thing ,the neutral thing develop opposite charge on them]
