The phenomenon of polarization explains the experiments on the attraction of light objects by an electrified body, for example, pieces of paper, dust particles. Although these objects are generally neutral, they become polarized in the electric field of an electrified body (glass or ebonite rod). At the end of a piece of paper closest to the stick, a bound charge of the opposite sign appears, and at the distant end, a charge of the same sign as on the stick. In this case, the electric field around the interacting bodies is inhomogeneous. The interaction of bodies in an inhomogeneous electric field leads to the attraction of pieces of paper to an electrified stick.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
