Hengdian Kim factory ---- isotropic and anisotropic magnetic material based on single-domain grain-oriented or not divided permanent magnet materials: isotropic material, the rough shape when single-domain grains are disordered ; anisotropic magnetic material prices, grain alignment in rough shape when under the influence of the orientation of the field are ordered. The basic principle of magnetic recording magnetic recording is to enter information into an electrical signal input to the recording head coil to thereby produce a corresponding change in the magnetic field in the gap at the head of the tape if The magnetic recording medium having a constant speed tight near the head gap through high-quality soft magnetic material, the change must be magnetic field due to hysteresis and will keep track corresponding to the input signal of the wholesale price of a soft magnetic material, which is a simple process of magnetic recording. Conversely, if the magnetic tape through a constant speed by the reproducing head gap, will induce a corresponding electrical signal to track changes in the magnetic head coil, amplified and then converted to the original input signal soft magnetic materials This is a magnetic read out the regeneration process. Hengdian Dongyang City, Kim Dae magnetic factory ---- how to shield or guiding magnetic field? Ferromagnetic materials can be used to shield the magnetic field, generally we use an ordinary iron. It should be noted that the thickness of the iron plate, if the thickness of less than iron in magnetic saturation, can only shield part of the field, the magnetic field lines emanating still be part of. The key guiding magnetic field forming a magnetic circuit that the choice of materials and the appropriate size and shape of the high permeability and reduce magnetic flux leakage, the magnetic circuit of the yoke and pole pieces reasonable configuration. Soft magnetic materials factory wholesale _ Kim Dae-magnetic smile (certified) _ Hubei soft magnetic material is provided by a large magnetic Hengdian gold plant.
