Alien magnet manufacturer: higher requirement of magnetic shielding need high permeability material

Special-shaped magnet manufacturer: higher requirement of magnetic shielding need high permeability material if the planet as a big magnet, the earth's magnetic North Pole is refers to the South Pole, pole is magnetic. Between the magnets and magnet, mutually exclusive, different magnetic poles with the same phase. Mutually exclusive, so, the compass and the South Pole ones and the arctic are exclusive, compass and behind the attraction. Magnet component is iron, cobalt, nickel and other atoms, the internal structure of the atom is more special, itself has a magnetic moment. Special-shaped magnet type: shape magnet: square shaped magnets, magnet, tile shaped magnets, cylindrical magnet, ring magnets, wafer magnets, magnet, magnet, magnet, magnetic frame attribute class magnet: samarium cobalt magnet, ndfeb magnet, ferrite magnets, alnico magnets, iron chromium cobalt magnet, industry type of magnet: magnets, magnetic components, motor, powerful magnets, magnetic, and so on rubber magnet type. Permanent magnet. Long magnet and magnetic, always. Long magnet is strong magnetic, combined to make the spin of magnetic materials and electronic angular momentum into fixed direction arrangement, soft magnetic is combined with electricity. ( Is also a kind of combined with magnetic method) Such as current remove soft magnetic iron will slowly lost. How much kinds of magnetic material in the world? Generally speaking, the magnetic material can be divided into magnetic resistance, paramagnetic, ferromagnetic and antiferromagnetic and ferrous magnetic. Our general ordinary iron plate for shielding the magnetic field. Higher requirements of magnetic shielding need high permeability material, meet the requirements of the material is iron nickel alloy, this material has the very high magnetic permeability. When you need to shield the magnetic field is very strong, only use single layer shielding materials, is not short of shielding requirements, will happen is saturated. Alien magnet manufacturer to tell you, when the field is changed, the length of the magnetic material and are small changes in volume, this phenomenon is called magnetostrictive. The length variation is called linear magnetostriction, the change of volume called magnetostrictive volume. Magnetostrictive volume is much weaker than linear magnetostriction, are generally mentioned magnetostrictive linear magnetostriction. Since magnetic materials with different magnetization state will produce scale, so if they use magnetized by alternating magnetic field, they will produce mechanical vibration. In this way, the electromagnetic energy is transformed into mechanical energy. Alien magnet manufacturer to tell you, this nature has been used to make various energy conversion devices, such as ultrasonic generator, sensors, etc. For the general common magnetic materials, magnetostrictive coefficient is small, only 0 30ppm。 But in recent years found that some rare earth iron made of a material has great magnetostrictive coefficient, reached more than 1000 PPM, because lead is called the big magnetostrictive materials or giant magnetostrictive materials. Advantage of the characteristics of the large magnetostriction, can produce a variety of power conversion devices, electromagnetic energy is converted into mechanical energy or vice versa.
