Cov yam ntxwv thiab kev siv ntawm cov khoom siv hlau nplaum mos

Cov yam ntxwv ntawm cov khoom siv mos sib nqus

Nyob rau hauv qis magnetic teb, magnetization muaj peev xwm ncav cuag 80% -90% ntawm nws saturation magnetization zog, uas txhais tau tias nws pib sib nqus permeability yuav tsum siab thiab saturation magnetization zog yuav tsum siab.

2. Tsis muaj (me me li sai tau) crystal anisotropy.

3. Lub sib nqus contraction tas li yuav tsum me me kom tsis txhob muaj kev ntxhov siab ua rau anisotropy; Cov no feem ntau yog cov khoom sib nqus mos ua los ntawm cov hlau lossis alloys.

Thaum siv nyob rau hauv alternating magnetic teb, hysteresis voj ntawm mos magnetic ntaub ntawv yuav tsum me me li sai tau, raws li qhov sib nqus poob yog proportional rau thaj tsam ntawm hysteresis voj. Ntawm qhov tsawg zaus, cov khoom sib nqus mos yuav tsum muaj qhov pib permeability siab, siab saturation magnetization, thiab qis coercivity. Txawm li cas los xij, thaum siv cov zaus ntau dua, qhov yuav tsum tau muaj rau siab saturation magnetization siv yog txwv. Thaum siv ntau zaus, qhov yuav tsum tau ua kom muaj kev tiv thaiv siab ntawm cov khoom sib nqus yog qhov tseem ceeb tshaj plaws vim tias qhov poob tam sim no yog proportional rau lub square ntawm zaus; Feem ntau lub nroog xaiv siv ferrite mos magnetic cov ntaub ntawv.

Daim ntawv thov ntawm Soft Magnetic Materials

1. Daim ntawv thov ntawm cov cuab yeej siv siab tam sim no feem ntau yog siv nyob rau hauv quasi-static lossis tsawg zaus, siab tam sim no; Hlau cores xws li electromagnets, fais fab transformers, motors, thiab lwm yam.

2. Daim ntawv thov ntawm cov khoom siv tsis muaj zog tam sim no feem ntau yog siv los ntawm cov khoom siv hluav taws xob siab thiab cov tsis muaj zog tam sim no. Piv txwv li, cov tub ntxhais sib nqus ntawm cov kav hlau txais xov coil hauv cov khoom siv sib txuas lus, cov tub ntxhais hlau ntawm cov me me transformers hauv hluav taws xob circuits, thiab lwm yam.
