1 A saturation magnetic flux density: (saturation magnetic flux density) magnetic body is magnetized to saturation when the magnetic induction intensity. In practice, the saturation magnetic flux density is often refers to a specified field (basically reached saturation when the magnetic field), the magnetic induction intensity.
2 remanent induction: From the magnetic body of the saturation, the magnetic field (including self-demagnetization field) monotone decreasing to 0 the magnetic induction intensity.
3 coercivity magnetic flux density, he is the saturation magnetization from the magnetic body of the state, along the saturation hysteresis loop monotonic change in magnetic field strength, so that the magnetic induction intensity B decreases to 0 when the magnetic induction intensity.
4 Intrinsic coercive force: From the magnetic body so that the saturation magnetization state of magnetization M of the magnetic field strength reduced to 0.
5 BH: In the permanent magnet demagnetization curve at any point on the magnetic induction intensity and the magnetic field strength of the product.
6 initial permeability: magnetic body in the magnetic neutral state, permeability limit.
7 Loss tangent: he was a complex series permeability of the imaginary part and real part of the ratio of its physical meaning of magnetic materials in alternating magnetic field of a weekly period, loss of energy and stored energy of the two faction ratio.
8 than the loss tangent: This is the material loss tangent and the ratio of initial permeability.
9 Temperature Coefficient: In between the two given temperature, the measured change in volume divided by the temperature variation.
10 permeability ratio of temperature coefficient: temperature coefficient of permeability and permeability ratio.
11 Curie temperature: at this temperature, the spontaneous magnetization is zero, that is, the ferromagnetic material (or sub-magnetic material) from ferromagnetic state (or ferrimagnetic state) into a paramagnetic state of the critical temperature.
