To'yinganlik magnit induksiya intensivligi Bs: Uning o'lchami materialning tarkibiga bog'liq va uning mos keladigan jismoniy holati material ichidagi magnitlanish vektorlari aniq joylashtirilgan.
Qoldiq magnit induksiya intensivligi Br: histerezis halqasidagi xarakterli parametr, H 0 ga qaytganda B qiymati.
Squareness ratio: Br∕Bs
Majburiy kuch Hc: Bu materialning magnitlanishining qiyinligini ko'rsatadigan miqdor bo'lib, materialning tarkibi va kamchiliklariga (iflosliklar, kuchlanish va boshqalar) bog'liq.
Magnetic permeability μ: is the ratio of B to H corresponding to any point on the hysteresis loop, and is closely related to the working state of the device.
Initial permeability μi, maximum permeability μm, differential permeability μd, amplitude permeability μa, effective permeability μe, and pulse permeability μp.
Kyuri harorati Tc: Ferromagnit moddalarning magnitlanishi harorat oshishi bilan kamayadi. Muayyan haroratga erishilganda, o'z-o'zidan magnitlanish yo'qoladi va paramagnetik bo'ladi. Kritik harorat Kyuri haroratidir. U magnit qurilmalar ishlaydigan yuqori chegara haroratini aniqlaydi.
Loss P: hysteresis loss Ph and eddy current loss Pe P = Ph plus Pe = af plus bf2 plus c Pe ∝ f2 t2 / , ρ decreases,
The method to reduce the hysteresis loss Ph is to reduce the coercive force Hc; the method to reduce the eddy current loss Pe is to reduce the thickness t of the magnetic material and increase the resistivity ρ of the material. The loss of the core in free still air is related to the temperature rise of the core as:
Umumiy quvvat sarfi (mVt) / sirt maydoni (sm2)
