2 NdFeB magnets which application? NdFeB permanent magnet with its excellent performance, abundant raw material and reasonable prices are to rapid development and wide application. The main applications in micro-motors, permanent magnet instrument, electronic industry, automobile, petrochemical, nuclear magnetic resonance devices, sensors, audio equipment, magnetic suspension system, magnetic transmission machine and magnetic therapy devices. Low 3 ferrite magnetic analog performance and the lowest price, good temperature characteristics, corrosion resistance, good cost performance NdFeB highest performance, price, strength, supply Rally magnets, no heat and corrosion SmCo high performance, the highest price, crisp, Rally magnet wholesale cost, temperature characteristics superior, Rally magnet Price, tolerance to low corrosion Alnico performance and in price, the temperature characteristics excellent corrosion resistance, interference and poor SmCo, Ferrite body, NdFeB sintered and bonded available method for manufacturing sintered magnetic high, Rally magnets, rather poorly, bonded magnet forming a good, much lower performance. Casting and sintering AlNiCo available manufacturing methods, high performance cast magnet, good moldability is poor, low sintered magnet, good moldability. Ferrofluid in a magnetic field generated by a neodymium magnet is located below the dishes were caused, showing normal field instability. When a paramagnetic fluid in vertical section of a sufficiently strong magnetic field, the surface naturally form a fold configuration. This remarkable effect is considered to have a normal field instability. The formation of wrinkles increases the surface free energy of the fluid and gravitational energy, but reduces the magnetic energy. Fold only when the magnetic field above the critical magnetic field will form, at this time to reduce the magnetic energy in the value exceeds the increase in the surface free energy and gravitational energy. Ferrofluid have unusually high susceptibility, a small bar magnet can achieve the critical magnetic field and to produce wrinkles.
