The development of China's current magnetic ranks first in the world, has become the world's largest permanent magnet material production in the country.
Magnetic
    Functional devices used in the magnetic sweeper manufacture of magnetic material called magnetic materials. The classification are: permanent magnet material (also called hard magnetic material), soft magnetic materials, semi-hard magnetic materials, magnetostrictive materials, magnetic thin film, magnetic fluid, etc., they are collectively referred to as functional magnetic material.
Permanent (hard) magnetic materials and soft magnetic materials
    Magnetic materials, also known as hard magnetic material when the magnetic field is removed, the material still having magnetism; soft magnetic material when the magnetic field is present, a high magnetic flux density, when the magnetic field removed, the loss of the magnetic materials. This does not refer to a hard and soft on the mechanical properties of the hard and soft, but rather on the magnetic properties of the hard and soft. After literally means applied magnetic magnetized magnetic material to be able to retain their ferromagnetic long (short magnetic), characterized in that the high coercive force. Coercivity magnetic material magnetized later that a residual magnetism after demagnetization (residual magnetic flux density and residual magnetization) of the magnetic field strength is reduced to zero. The soft magnetic material is both easy magnetization of magnetic field, and easy to demagnetization, the low coercivity magnetic material. Refers to the applied magnetic field demagnetization (referred to as magnetic field) after magnetizing the magnetic material, combined with the Drawer magnets  of the magnetic field in the opposite direction to decrease the magnetic field.
Bonded permanent
    Bonded permanent plasticity refers to the binder material is a blend of the permanent magnetic powder to plastic powder, through a variety of plastic materials molding process to obtain a composite magnetic body. In the whole process of forming the adhesive physical changes occur, with the powder particles together and made of magnet is called a bonded magnet.
Sintered Magnet
    Application of powder metallurgy, materials made of powder will burn, molding made of rough, then made of sintered magnets.
Neodymium iron boron (NdFeB)
    Is a new kind of magnetic material NdFeB ternary intermetallic compounds, is all magnetic materials magnetic energy per unit volume contains the largest of a permanent magnet material. Made of NdFeB bonded magnet powder with this the magnets can be strong, temperature stable performance, high precision forming of complex shapes without the need for post-processing of parts, and has good corrosion resistance and good toughness, widely used in computer disk drives voice coil motor (VCM), magnetic resonance imaging (MRI) equipment and a variety of audio-visual equipment, microwave communications, magnetic machine (magnetic pump, magnetic valve), household appliances and maglev trains and other fields.
Ferrite
    Ferrite is iron oxide (Fe2O3) based oxides of other elements reaction of a ferrous compound.
Calcined ferrite material
    Iron oxide red (or iron scale) and strontium or barium carbonate and a small amount of materials, according to a composition ratio after mixing, at a certain temperature below the sintering atmosphere, through a raw material in the solid phase reaction between MO6Fe2O3 (where M as Sr, Ba) ferrite.
Ferrite Materials
    Ferrite material is strontium ferrite and barium ferrite, ingredients SrFe12O19 and BaFe12O19. Has a magnetic quality, high cost performance, good stability, is the world's largest amount of magnetic functional materials. Widely used in permanent magnet motors, speakers, and magnetic retention, electronic deflection, etc., including automotive, communications, audio, video recorders, televisions, radios, microwave ovens, refrigerators, magnetic separation equipment, medical equipment, computer peripherals, office automation equipment, children's toys, and many other fields.
Isotropic and anisotropic materials
    Permanent magnet materials based on single-domain grain orientation were divided into: isotropic material, rough shape when single-domain grains are disordered; anisotropic materials, grain rough shape when under the effect of the orientation field arrangement is orderly.
Magnetic Recording
    The basic principle is that the magnetic field into electrical signals input to the recording head to the coil, so that the gap at the head produce a corresponding change in the magnetic field, if this magnetic recording medium having a magnetic tape at a constant speed immediately adjacent to the head through gap, the magnetic field must be the change magnetization hysteresis and will remain as the input signal corresponding to the track, which is a simple recording process. Conversely, if the magnetic tape after a certain speed is achieved by the reproducing head gap, the magnetic head coil will induce a change in the track corresponding to the electrical signal is amplified and then converted to the original input signal, which is magnetic read out the regeneration process.
Nano-magnetic materials
    A nanometer is 10-9 meters middleweight, will nanoscale magnetic material powder whose performance has changed fundamentally, the main applications are: nanocomposite permanent magnetic materials, permanent magnetic materials and soft magnetic materials by mixing powder then After processing, the permanent magnet material can be very high magnetic properties. Also made of powder particles of the material to achieve sub-micron level, with Chengchou structure, excellent performance can be obtained permanent magnet. It can increase the production of magnetic recording materials than dry sound, improving image quality; made of magnetic liquid is a very good sealing material.
