Ningbo Tengxiao Magnetic Industry Co., Ltd. is a professional supplier of magnetic products and magnetic equipment, specializing in the production of high-quality pot magnets, magnetic badges and other magnetic equipment, as well as custom industrial magnets.

The terminology of magnet:

1 Saturation magnetic induction intensity: (saturation magnetic flux density) the magnetic induction intensity when a magnetic body is magnetized to a saturated state. In practical applications, saturation magnetic induction often refers to the magnetic induction under a certain specified magnetic field (basically the magnetic field when magnetic saturation is reached).

2 Residual magnetic induction: From the saturation state of the magnetic body, the magnetic field (including self-demagnetizing field) is monotonously reduced to 0.

3 Magnetic flux density coercive force, which is the magnetic induction intensity when the magnetic field intensity is changed monotonously along the saturation hysteresis loop from the saturation magnetization state of the magnetic body, so that the magnetic induction intensity B is reduced to 0.

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 intensity and magnetic field intensity at any point on the demagnetization curve of a permanent magnet.

6 Initial permeability: the limit value of the permeability of the magnetic body in the magnetic neutral state.

7 Loss tangent: it is the ratio of the imaginary part and the real part of the series complex permeability. Its physical meaning is the ratio of the loss energy to the stored energy of the magnetic material in each cycle of the alternating magnetic field.

8 Specific loss tangent: This is the ratio of the loss tangent of the material to the initial permeability.

9 Temperature coefficient: Between two given temperatures, the measured change is divided by the temperature change.

10 The specific temperature coefficient of permeability: the ratio of the temperature coefficient of permeability to the permeability.

11 Curie temperature: At this temperature, the spontaneous magnetization is zero, that is, the critical temperature at which a ferromagnetic material (or submagnetic material) changes from a ferromagnetic state (or ferrimagnetic state) to a paramagnetic state.
