Special-shaped magnet manufacturers take you understand the assumptions that the magnetization magnet material gradually magnet magnetized magnetic materials and with the increase of magnetic field, magnetic induction intensity will increase accordingly, until the saturated state. Figure curve O - magnet magnetization process can be used a - b - C said. Gradually reduce the external magnetic field, magnetic abnormity material change, if the external magnetic field is reduced, will surely make magnet material of magnetic induction is reduced, but the magnetic induction is not along the c - b - A return to the original road, but along the curve c - d - E is reduced. From the saturation point decreases when the external magnetic field, the corresponding magnetic induction is higher than the initial magnet magnetization of magnetic induction, seems to be the decrease of the magnetic induction behind the reduce of the magnetic field. This feature is called hysteresis phenomenon of magnetic materials, is an important feature of magnetic materials. The external magnetic field changes of plus or minus one week, the magnetic induction along the c - d - e- f - g - h - 我- - - - - - j - C change for a week, the closed curve is called the hysteresis loop. The area of the hysteresis loop contains on behalf of the external magnetic field on the material to do the work, known as hysteresis losses. Without additional magnetic field, magnetic neutral state, special-shaped magnet material inside the magnetic moment of a chaotic arrangement, the total magnetic moment is zero, so the material of magnet magnetization is zero. When magnetic materials in plus a magnetic field, the inside of the material magnetic moment is the force of the magnetic field, the magnetic moment will turn towards the direction of the external magnetic field, just as a magnet in the magnetic field rotation. Magnetic moment will no longer be completely chaotic arrangement at this time, but along the external magnetic field to produce a general magnet magnetization direction, was magnet magnetized material. Inside the magnetic moment of the external magnetic field, the greater the material to the more the number of the external magnetic field direction and degree. Magnetic material inside all the magnetic moment will be lined up along the external magnetic field direction, foreign material shows the magnet magnetization reaches the maximum value, material is the magnet magnetized to saturation. Saturated, no matter how to increase the magnetic field, the material of magnet magnetization and no longer increases. So material is magnet magnetized to saturation of magnet magnetization called magnet saturation magnetization, represented by Ms. Project general magnet magnetization - magnet magnetization curve, the relationship between magnetic field and magnetic induction intensity for - the relationship of the magnetic field magnet magnetization curve. Magnetic saturation is a saturated magnetic induction intensity, expressed in Bs. We know the material of magnet magnetization change with the external magnetic field. In scientific experiments and production practice, often think of the relationship between magnetic field and magnet magnetization curve, known as the magnet magnetization curve, as shown. Among them, the order of the size of the external magnetic field, the ordinate said magnet magnetization. Magnet magnetization curve in general can be divided into three stages: reversible stage of magnet magnetization and irreversible phase of magnet magnetization and saturation stage.
