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 wholesale price, 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 remain corresponding to the input signal of the track, which is a simple process of magnetic recording. Conversely, if the magnetic tape through at 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, which is magnetic read out the regeneration process. Magnetization curve of magnetic material magnetic Hengdian Kim factory ---- magnetic material is made of ferromagnetic material or ferrimagnetic material composition, in the role of an external magnetic field H, there must be a corresponding magnetization M or soft magnetic induction B magnetic materials, which varies with the magnetic field strength H curve is called the magnetization curve (M ~ H or B ~ H curve). Magnetization curve is generally non-linear, has two characteristics: magnetic saturation and hysteresis. That is, when the magnetic field strength H is large enough, the magnetization M reaches a certain saturation value Ms, continues to increase H, Ms unchanged; and when the material reaches the saturation value of M, when the external magnetic field H is reduced to zero, M and is not set to zero, but along MsMr curve. Working state of the material corresponds to a certain point, this point is often referred to as the operating point M ~ H curve or B ~ H curve.
