Nd-Fe-B magnets and magnetic role

First, the history of the magnetized water

Four basic nature of magnetic force is one of the four great inventions in ancient China, one of the compass, is the ingenious application of the magnetic example. Physician Li Shizhen in the early Ming Dynasty 500 years ago found that the magnetic treated water is "to sore fistula, a long skin," and "there is a long drink of, and are advised to liquor," and "impotence" effect ( see the "Compendium of Materia Medica" pages 583-586), to keep fit, the treatment of many diseases. However, the ancients used by naturally occurring magnetic material is a natural magnet - magnetite, and its magnetic properties of magnetic materials with modern synthetic compared with very low.

Second, the strongly magnetic high Wang - NdFeB

In 1983, the third generation of Nd-Fe-B Na-Fe-B birth of their ordinary magnet magnetic field intensity is more than 10 times, up to more than 10 years of life, human society is so far found energy product (MGOE) the highest-yong Magnetic materials, known as "PM Wang." Widely used in national defense and space technology, microwave, communications, electronics, health care and other high-tech fields.
