The Conversion Of Magnets And The Main Components

  The conversion of magnets and the main components

  The conversion of magnets

  Unmagnetized magnet internal magnetic molecules (molecular magnet theory) is arranged irregularly, after the magnetization process after the magnetic molecules will have a regular arrangement. At this time, the N pole and the S pole of the magnetic molecules are magnetized to the magnet in the same direction. At the same time, there are opposite poles on the same magnet and the magnetic quantities of the poles are equal.

  The main ingredient

  Magnet, also known as iron, refers to the surrounding and its own internal existence of magnetic objects or materials, divided into natural and man-made two categories. Artificial magnets are usually made of metal alloy, with a strong magnetic. Can be divided into "non-permanent magnet" and "non-permanent magnet", that is, "hard magnetic" and "soft magnetic." Natural magnet main components: iron oxide, chemical formula Fe3O4, commonly known as "magnetic iron oxide." A black crystal with magnetic properties. Can be seen as ferrous oxide and iron oxide composition of the compound. Because there are two different valence states in the crystals of ferric oxide, one third is Fe2 + and two thirds is Fe3 +, which is a complex compound. It is insoluble in water and can not react with water. Reaction with acid, insoluble in alkali. Mainly for the system primer and topcoat, for the electronics industry, magnetic materials, but also for the construction industry, anti-rust agent.
