Rare earth permanent magnet materials and health care

We mankind's survival of the Earth's magnetic field has a pet. The human body is full of ferromagnetic material, biological also current biological magnetic field, when stimulated by the strong magnetic field will have many delicate biological reaction that resulted in a medical diagnosis and magnetic field therapy.

In the rare earth neodymium and samarium, and other special atomic structure, is the quality of the essential ingredient for permanent magnet materials. Especially the generation of magnetic Wang NdFeB the emergence of not only given rise to many electronic and mechanical industrial products a revolutionary change, but also for the medical diagnostic equipment and the magnetic "magnetic" has scaled to a new height.

Hospitals with the magnetic resonance imaging instrument than the CI to a new type of sophisticated diagnostic equipment. Composition of the various elements of human cells have nuclei with nuclear magnetic moment, in the strong magnetic field must have resonance, use of the body's normal tissue resonance with lesions late Henan different times, the precision of the CT scan, using reflection of the Images will be able to observe the differences in the early diagnosis of small lesions. But the equipment requires a strong magnetic field systems support. The use of superconducting magnet, with the need expensive ultra-low-temperature systems, installation and maintenance are very complicated and the use of ferrite magnets general, the need for dozens of tons, 100 tons or even to the magnet assembly into a monster. Using high-performance Nd-Fe-B permanent magnet material will be able to overcome the above drawbacks, only 23 tons magnet, the overall volume significantly reduce duplication and, in ensuring high-quality and high-resolution under the condition of the equipment to achieve the small size and light is conducive to promoting the use of.
