If you press the atomic current explanation is that magnetic magnetization magnetized objects other objects generate an electric field generated by the current interaction of the electric field generated force of the material are mostly composed of molecules, molecules are made up of atoms, and atoms in turn determined by the characteristics of the magnet nuclei and electrons. In the atom, the electron stop rotation, and rotation around the nucleus. Both motion of electrons will have magnetic properties. However, in most substances, the direction of electron motion vary, disorganized and magnetic effects cancel each other out. Thus, most of the substances under normal circumstances, does not exhibit magnetic properties. Iron, cobalt, nickel or ferrite ferromagnetic substances different, it inside the electron spin can spontaneously line up in a small area, forming a spontaneous magnetization area, this area is called the spontaneous magnetization of the magnetic domains. Magnetization of ferromagnetic substances, the internal magnetic domains neatly lined up in unison direction, the magnetic strengthened constitute a magnet. Magnet iron absorption process is the magnetization process of iron, between the magnetized iron and magnets of different polarity appeal, iron will and the magnet firmly "stick" together.
　　Natural magnets are iron oxide and artificial magnets are usually steel. After a magnetized steel will remain natural permanent magnet magnetic generally refers not only ferrites (three Fe3O4), as well as iron-cobalt-nickel alloy, iron-rare earth permanent magnet materials of various alloys, such as aluminum, nickel and cobalt, SmCo, NdFeB, these are also very common, very strong magnetic properties, these substances can be magnetized magnetic field constant magnetic field, and magnetic magnetized itself has not disappeared. Artificial magnet component is based on a variety of metal is magnetized performance, according to needs. Magnet proximity (touch) magnetic substance that is close to one end of the induction into Synonyms pole, while the other end of the pole is generated with the same name.
