Cov tuam txhab hlau nplaum muaj zog qhia koj tias hom ferrite hlau nplaum tuaj yeem muab faib ua li cas? Raws li cov khoom sib nqus sib txawv thiab cov ntawv thov, ferrite tuaj yeem muab faib ua: gyromagnetic, torque magnetic, mos sib nqus, ruaj khov sib nqus, piezoelectric magnetic, hard magnetic thiab lwm yam.
1. Gyromagnetic cov ntaub ntawv
Lub gyromagnetism ntawm cov khoom sib nqus yog hais txog qhov tshwm sim uas nyob rau hauv qhov tshwm sim ntawm ob qho tib si perpendicular ruaj khov magnetic teb thiab electromagnetic yoj magnetic teb, txawm hais tias lub dav hlau-polarized electromagnetic tsis propagate nyob rau hauv ib tug tej yam kev taw qhia nyob rau hauv cov khoom, lawv polarization dav hlau yuav txuas ntxiv tig ib ncig. kev taw qhia ntawm kev nthuav tawm. Txawm hais tias cov ntaub ntawv hlau thiab hlau kuj tseem muaj qee qhov ntawm gyromagnetism, lawv tsis tuaj yeem siv vim tias tsis muaj kev tiv thaiv thiab kev poob tam sim no loj heev, thiab electromagnetic tsis tuaj yeem nkag mus rau hauv lawv sab hauv. Yog li ntawd, daim ntawv thov ntawm gyromagnetism nyob rau hauv ferrite gyromagnetic cov ntaub ntawv tau los ua ib tug tshwj xeeb teb ntawm ferrite. Feem ntau ntawm cov ntaub ntawv gyromagnetic yog ua ke nrog waveguides lossis cov kab sib kis uas thauj cov microwaves los ua ntau yam khoom siv microwave. Nws yog tsuas yog siv hauv cov khoom siv hluav taws xob xws li radar, kev sib txuas lus, navigation, thiab telemetry.
2. Momental magnetic data
Qhov no yog hais txog cov ntaub ntawv ferrite nrog lub voj voos hysteresis. Nws cov yam ntxwv yog tias thaum muaj cov nyhuv me me sab nraud sib nqus, nws tuaj yeem sib nqus thiab ua tiav. Tom qab tshem tawm sab nraud magnetic teb, cov hlau nplaum tseem zoo li qub thaum nws puv. Xws li magnesium manganese ferrite, lithium manganese ferrite thiab lwm yam. Cov khoom siv ferrite no tsuas yog siv rau hauv nco cores ntawm ntau lub khoos phis tawj hluav taws xob, thiab lwm yam.
3. Cov ntaub ntawv sib nqus mos
Cov khoom no yog ib qho yooj yim rau magnetize thiab demagnetize nyob rau hauv ib tug qaug zog magnetic teb, xws li zinc chromium ferrite thiab nickel zinc ferrite. Mos ferrite yog ib yam khoom siv ferrite nrog dav daim ntawv thov, ntau hom, ntau qhov ntau thiab cov zis ntau.
4. Permanent hlau nplaum ferrite
Hexagonal compound nrog uniaxial anisotropy. Feem ntau barium, strontium, coj peb ferrites thiab lawv cov kev daws teeb meem sib xyaw. Muaj homosexual magnetism thiab heterosexual magnetism. Vim tias cov khoom siv ferrite no tseem tuaj yeem khaws cov khoom muaj zog thiab ruaj khov rau lub sijhawm ntev tom qab qhov chaw magnetization sab nraud ploj mus, nws tuaj yeem siv los tsim qhov chaw sib nqus tas li rau qhov chaw sab nraud. Nws yog dav siv, piv txwv li, nws yog siv los ua cov hlau nplaum ruaj khov hauv ntau lub ntsuas hluav taws xob, cov tshuab hluav taws xob, xov tooj, hais lus, TV thiab cov khoom siv microwave.
5. Piezomagnetic cov ntaub ntawv
Cov khoom siv no yog hais txog cov khoom siv ferrite uas yog mechanically elongated los yog luv luv nyob rau hauv cov kev taw qhia ntawm magnetic teb thaum lub sij hawm magnetization, xws li npib tsib xee-zinc ferrite, npib tsib xee-tooj liab ferrite thiab nickel-chromium ferrite. Cov ntaub ntawv piezomagnetic feem ntau yog siv los ua cov transducers rau kev sib hloov ntawm electromagnetic zog thiab txhua yam zog, thiab raws li magnetoelastic ntsiab rau ultrasound.
6. Cov khoom siv hlau nplaum nyuaj
Ferrite hard magnetic cov ntaub ntawv tsis yooj yim rau demagnetize tom qab magnetization, yog li lawv tseem hu ua cov khoom sib nqus ruaj khov lossis cov khoom sib nqus ruaj khov. Xws li barium ferrite, ferrite thiab lwm yam. Nws yog tsuas yog siv nyob rau hauv recorders, pickups, hais lus, sib nqus cores ntawm ntau yam twj paj nruag, thiab lwm yam nyob rau hauv telecommunication khoom.
