Why do pieces of paper

The bits will be attracted to the rod. This demonstration involves two phenomena, triboelectricity — the transfer of charge from one object to another by friction, and polarization by induction — the redistribution of charge on an object by placing it near a charged object, that are illustrated by subsequent demonstrations. See, for example, It comes first, however, for historical reasons.

In B. We now know that this ability arises from the fact that after one rubs amber with wool, the amber becomes electrically charged and so does the wool, with opposite charge.

Blog Outsets and onsets! Read More. November 08, To top. 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. Here, see the electric field. The same polarities do not like each other:. As none of the answers posted earlier are correct, I am just reproducing what Feynman had explained The Feynman Lectures in Physics, Vol.

A surprisingly complicated problem in the theory of dielectrics is the following: Why does a charged object pick up little pieces of dielectric?

If you comb your hair on a dry day, the comb readily picks up small scraps of paper. If you thought casually about it, you probably assumed the comb had one charge on it and the paper had the opposite charge on it.

But the paper is initially electrically neutral. It is true that sometimes the paper will come up to the comb and then fly away, repelled immediately after it touches the comb.
