  • Magnetic Induction B and Magnetic Polarization J

Magnetic Induction B and Magnetic Polarization J

Magnetic Induction B and Magnetic Polarization J Practice and theory have proved that when a ferromagnetic or ferrimagnetic substance is magnetized in a magnetic field, in addition to the magnetic field in the substance, because the magnetic moments of the atoms of the ferromagnetic substance turn to the direction of the external magnetic field, it [...]

  • Hysteresis Curve and Intrinsic Demagnetization Curve (B-H Curve and J-H Curve)

Hysteresis Curve and Intrinsic Demagnetization Curve (B-H Curve and J-H Curve)

Hysteresis Curve and Intrinsic Demagnetization Curve (B-H Curve and J-H Curve) Permanent magnet materials have two notable features, one is that they can be strongly magnetized under the action of an external magnetic field, and the other is hysteresis, that is, the material remains magnetized after the external magnetic field is removed. The relationship between [...]

  • Factors and Methods Affecting the Performance of NdFeB Magnetic Materials

Factors and Methods Affecting the Performance of NdFeB Magnetic Materials

Factors and Methods Affecting the Performance of NdFeB Magnetic Materials Since the advent of NdFeB permanent magnet materials, it has attracted much attention due to its superior magnetic properties. promote. We generally use remanence, coercive force and maximum energy product to measure the performance of magnetic materials. Remanence Br If the magnet is likened to [...]

  • Strong Magnet Performance Curve

Strong Magnet Performance Curve

Strong Magnet Performance Curve, Demagnetization of Permanent Magnets, Demagnetization curves for a Nd-Fe-B The value of the reverse magnetic field strength required to reduce the magnetic induction to zero when the magnet is magnetized by reverse magnetization in the reverse magnetization is called the magnetic coercive force (Hcb). However, the magnetization of the magnet is [...]
