Study on application of new type revolving magnetic needle

摘要

With Hc>=17000 Oe, (BH)max >=42MGOe, revolving magnetic needle is made of agglomeration Nd-Fe-B permanent magnetic materials. Optimization design generates the maximum magnetic field with pyramid needle-like permanent magnet. With micro motor (rotary speed=2000-3000r/m), 220V or 110V photoelectric power source and high-octane Ni-MH battery, the revolving magnetic needle is integrated with vibrating massage, acupuncture and magnetic medical care to prevent as well as overcome sickness. It is proved by many famous hospitals that it is effective in 95
