Magnet component is iron,cobalt,nickel and other atoms,the internal structure of the atom is more special,itself has a magnetic moment.Magnet type:shape magnet:square shaped magnets,magnet,tile shaped magnets,cylindrical magnet,ring magnets,wafer magnets,magnet bar magnets,magnetic frame,magnet:attribute class samarium cobalt magnet,ndfeb magnet,ferrite magnets,alnico magnets,iron,chromium cobalt magnet industry class magnet:magnets,magnetic components,motor,powerful magnets,magnetic,and so on rubber magnet type.Permanent magnets and magnetic magnet points,and permanent magnet is coupled with strong magnetic,make the spin of magnetic materials and electronic angular momentum into fixed direction arrangement,soft magnetic is combined with current such as(is also a kind of combined with magnetic method)current remove soft magnetic iron will slowly lost.

Can produce magnet magnetic field,has attracted ferromagnetic materials such as iron,nickel,cobalt and other metallic properties.

The halfway point of the bar magnet with thread hanging up,still,it will ends of each point to the earth's north and south,pointing to the north called refers to the North Pole or at the end of the N pole,pointing to the south is refers to the South Pole or at the end of the S pole.

If the earth as a big magnet,the earth's magnetic North Pole is to point to the South Pole,pole is magnetic.Between the magnets and magnets,with a rejection,heteropolar phase.Mutually exclusive,so,the compass and the South Pole ones and the arctic are exclusive,compass and behind the attraction.

Magnet can be divided into categories:"permanent magnet"and"non permanent magnets".A permanent magnet can be a natural product,also called lodestone,can also be made by human.The permanent magnet,such as the electromagnet,only under certain conditions will be magnetic.
