Electromagnetic radiation is generated alternately by electric field and magnetic field, which constitutes an electromagnetic field and propagates in a certain related direction in the form of waves. Electromagnetic waves can make the basic particles of an object rotate and displace.
Matter consists of particles (electrons, ions, atoms, molecules, dipoles, magnetic domains, etc.). ). The positive and negative charges or magnetic domains carried by these particles are disordered, so they do not show electricity and magnetism from a macro perspective. When external electromagnetic waves act on these particles. The positive and negative charges or the north and south poles of these particles are rearranged under the action of external electromagnetic waves, and the particles are rotated and displaced, that is, polarized or magnetized, and the balance is broken. The rotation and displacement of particles consume external electromagnetic wave energy in the form of heat. Polarized or magnetized particles produce current or magnetic current at the same time, resulting in secondary radiation field or scattering field. The interaction between the scattering field and the incident electromagnetic field leads to the distribution change of the total field, resulting in the "traction" absorbing effect.
Scraper is a kind of composite absorbing material made of many rare elements through special technology, which is very sensitive to electromagnetic waves. Incident electromagnetic waves are particularly easy to cause microscopic particles to rotate and shift, which will consume electromagnetic energy, thus realizing the absorption of electromagnetic radiation. (For details, please refer to the test report of scraping accessories series by Moore Laboratory, an international authoritative testing organization. )
Scraping tablets are designed for people to wear on their chests, in the form of necklaces and pendants. It can "pull" all kinds of harmful electromagnetic waves radiated to the scraper and its surroundings, and convert electromagnetic wave energy into heat energy. Therefore, scraping tablets can not only scrape, but also be used as ornaments, and also have the functions of preventing the harm of electromagnetic radiation and protecting human health.
