Ferrite waa oksaydh bir ah oo ah daawaha birta ah.Marka la eego xagga korontada, ferrites waxay leeyihiin iska caabin aad uga weyn marka loo eego isku-dhafka daawaynta birta, sidoo kale waxay leeyihiin sifooyin dielectric ah.Tamarta magnetic mugga halbeegga ferritku wuu hooseeyaa Marka inta jeer ee sarreeya la ururiyo, tamarta magnetic mugga halbeegga ferite waa hooseeyaa.(Bs) sidoo kale waa mid hooseeya (kaliya 1 / 3 ~ 1 / 5 ee birta saafiga ah), taas oo xaddidaysa kala duwanaanta xulashada waxayna xaddidaysaa baahida ballaaran ee baahida, waxaana si ballaaran loo isticmaali karaa codsiyada hadda jira ee xooggan ee dhinacyada kala duwan.
Ferrite waxaa laga soosaaray oksaydhyada birta iyo maaddooyinka kale.Guud ahaan, waxa loo qaybin karaa saddex nooc: ferrite joogto ah, ferrite jilicsan iyo gyromagnetic ferrite.
Magnet ferrite ee joogtada ah waxaa sidoo kale loo yaqaan magnet ferrite, taas oo ah magnetka madow ee yar ee aan inta badan aragno.Alaabta ceeriin ee ugu weyn waa bir oxide, barium carbonate ama strontium carbonate.Ka dib markii magnetization, xoogga garoonka magnetic haraaga waa mid aad u sarreeya, iyo garoonka magnetic haraaga waa la sii hayn karaa muddo dheer.Caadi ahaan waxaa loo isticmaalaa sida walxo magnet joogto ah.Tusaale: magnets-ka hadalka.
ferrite jilicsan ayaa lagu diyaariyaa oo lagu miisaamaa ferric oxide iyo hal ama dhowr oksijiinta birta ah (tusaale: nikkel oxide, zinc oxide, manganese oxide, magnesium oxide, barium oxide, strontium oxide, iwm.).Waxaa loogu yeeraa birlab jilicsan sababtoo ah marka goobta magnetization-ka ay meesha ka baxdo, waxaa jira wax yar ama ma jiraan goob magnet ah oo hadha.Caadi ahaan waxaa loo isticmaalaa sidii gariiradda ceejin, ama xudunta beddelka soo noqnoqda dhexdhexaadka ah.Tani gabi ahaanba way ka duwan tahay ferrite joogtada ah.
Gyromagnetic ferrite waxaa loola jeedaa walxo ferrite leh oo leh astaamo gyromagnetic.Gyromagnetism-ka agabka magnetic-ku waxa uu tilmaamayaa ifafaale in diyaaradda polarization of a air-polarized mowjadda koronto-magnet-ka ee ku faafto jihada gaar ah gudaha maaddada hoos fal ee labada siman siman DC field magnetic iyo hirarka korantada ee magnetic fields.Gyromagnetic ferrite ayaa si weyn loogu isticmaalay goobta isgaarsiinta microwave.Marka loo eego nooca crystal, gyromagnetic ferrite waxaa loo qaybin karaa nooca lafdhabarta, nooca garnet iyo nooca magnetoplumbite (nooc laba geesood ah) ferrite.
Qalabka magnetka ayaa si weyn loo isticmaalaa waxaana loo isticmaali karaa electro-acoustic, isgaarsiinta, mitirka korontada, matoorada, iyo sidoo kale qaybaha xusuusta, qaybaha microwave, iwm. Waxaa loo isticmaali karaa in lagu duubo luqadda, muusikada, iyo cajaladaha macluumaadka sawirka, qalabka kaydinta magnetka. kombiyuutarada, iyo kaadhadhka magnetka ee foojarrada fuulitaanka rakaabka iyo dejinta qiimaha.Kuwa soo socdaa waxay diiradda saarayaan alaabta magnetic loo isticmaalo cajaladda magnetic iyo mabda'a ficilka.
