The introduction to powerful magnets principle

　　The material is mostly composed of molecular composition. Molecule is made up of atoms. And atom is made up of a nucleus and electrons.

　　In the interior of the atom, electronic does non-stop rotation, around the atomic nucleus. These two electronic movement of will produce magnetic. But in the majority of substances, the direction of the electron motion is disorganized, and magnetic effects cancel each other out. Therefore, most substances, under normal circumstances, do not exhibit magnetic.

　　According to magnetic products factor, iron, cobalt, nickel or ferrite ferromagnetic substances differ. Internal electron spin can be spontaneously in a small area lined up to form a spontaneous magnetization zone, this spontaneous magnetization zone is called magnetic domains.

　　After ferromagnetic material is magnetized, internal magnetic domain is lined up neatly, with the same direction. So the magnetic gains enhancement, that constitutes a strong magnet. Magnet iron absorption process is the magnetization process of iron magnetized iron and magnets of different polarity attractive piece of iron firmly magnets "stick" together.
