1 Saturation magnetic induction intensity: (Saturation magnetic flux density) The magnetic induction intensity when a magnetic body is magnetized to a saturation state. In practical applications, the saturation magnetic induction intensity often refers to the magnetic induction intensity in a specified magnetic field (basically the magnetic field when magnetic saturation is reached).
2 Residual magnetic induction intensity: From the saturation state of the magnetic body, the magnetic induction intensity (including the self-decreasing magnetic field) is monotonously reduced to 0.
3 The coercive force of the magnetic flux density. It is the magnetic induction intensity when the magnetic field intensity is monotonously changed from the saturation magnetization state of the magnetic body along the saturation hysteresis loop to reduce the magnetic induction intensity B to zero.
4 Intrinsic coercive force: The magnetic field strength that reduces the magnetization M to 0 from the saturation magnetization state of the magnetic body.
5 Magnetic energy product: The product of magnetic induction and magnetic field strength at any point on the demagnetization curve of a permanent magnet.
6 Initial magnetic permeability: The limit value of the magnetic permeability of a magnetic body in a magnetically neutral state.
7 Loss tangent: It is the ratio of the imaginary part and the real part of the complex permeability in series. Its physical meaning is the ratio of the two sides of the loss energy to the stored energy in each period of the alternating magnetic field of the magnetic material.
8 Specific loss tangent: This is the ratio of the material's loss tangent to the initial permeability.
9 Temperature coefficient: Between two given temperatures, the measured change is divided by the temperature change.
10 Specific temperature coefficient of magnetic permeability: The ratio of the temperature coefficient of magnetic permeability to the magnetic permeability.
11 Curie temperature: At this temperature, the spontaneous magnetization is zero, that is, the critical temperature at which the ferromagnetic material (or ferromagnetic material) changes from a ferromagnetic state (or ferrimagnetic state) to a paramagnetic state.
