I-Ferrite yi-oxide yesinyithi eyenziwe nge-ferrous alloy. Ngokuphathelele umbane, ii-ferrites zinamandla okumelana kakhulu kunee-elemental metal alloy compositions, kwaye zineempawu ze-dielectric. Amandla emagnethi ngeyunithi nganye ye-ferrite aphantsi Xa i-frequency ephezulu iqokelelwe, amandla emagnethi ngeyunithi nganye ye-ferrite aphantsi. (Bs) ikwanamandla aphantsi (yi-1/3 ~ 1/5 yesinyithi esicocekileyo kuphela), ethintela uluhlu lwezinto ezikhethiweyo kwaye inciphise uluhlu olubanzi lweemfuno, kwaye ingasetyenziswa ngokubanzi kwizicelo zamandla aqhelekileyo kwiindawo ezahlukeneyo.
I-Ferrite ixutywe nee-iron oxides nezinye izithako. Ngokubanzi, inokwahlulwa ibe ziintlobo ezintathu: i-ferrite esisigxina, i-ferrite ethambileyo kunye ne-ferrite ye-gyromagnetic.
I-ferrite yemagnethi esisigxina ikwabizwa ngokuba yi-ferrite magnet, eyimagnethi emnyama encinci esihlala siyibona. Izinto zayo eziphambili yi-iron oxide, i-barium carbonate okanye i-strontium carbonate. Emva kwemagnethi, amandla e-residual magnetic field aphezulu kakhulu, kwaye i-residual magnetic field inokugcinwa ixesha elide. Ihlala isetyenziswa njengezinto zemagnethi ezisisigxina. Umzekelo: iimagnethi zesipikha.
I-ferrite ethambileyo ilungiswa kwaye ingcoliswe yi-ferric oxide kunye ne-oxide enye okanye ezininzi zesinyithi (umzekelo: i-nickel oxide, i-zinc oxide, i-manganese oxide, i-magnesium oxide, i-barium oxide, i-strontium oxide, njl.njl.). Ibizwa ngokuba yi-soft magnetic kuba xa i-magnetizing magnetic field inyamalala, akukho magnetic field incinci okanye akukho. Ihlala isetyenziswa njenge-choke coil, okanye i-core ye-intermediate frequency transformer. Oku kwahluke ngokupheleleyo kwi-ferrite esisigxina.
I-Gyromagnetic ferrite ibhekisa kwisixhobo se-ferrite esineempawu ze-gyromagnetic. I-gyromagnetism yezinto ze-magnetic ibhekisa kwinto yokuba i-plane ye-polarization ye-plane-polarized electromagnetic wave isasazeka kwicala elithile ngaphakathi kwesixhobo phantsi kwesenzo see-DC magnetic fields ezimbini ezithe nkqo kunye nee-electromagnetic wave magnetic fields. I-Gyromagnetic ferrite isetyenziswa kakhulu kwicandelo lonxibelelwano lwe-microwave. Ngokwe-crystal type, i-gyromagnetic ferrite inokwahlulwa ibe yi-spinel type, i-garnet type kunye ne-magnetoplumbite type (hexagonal type) ferrite.
Izinto zemagnethi zisetyenziswa kakhulu kwaye zingasetyenziswa kwi-electro-acoustic, kwii-telecommunications, kwiimitha zombane, kwiimoto, nakwizinto zememori, kwizinto ze-microwave, njl. Zingasetyenziselwa ukurekhoda ulwimi, umculo, kunye neeteyiphu zolwazi lomfanekiso, izixhobo zokugcina imagnethi kwiikhompyutha, kunye namakhadi emagnethi kwiivawutsha zokukhwela abakhweli kunye nentlawulo yeendleko. Oku kulandelayo kugxile kwizinto zemagnethi ezisetyenziswa kwiteyiphu yemagnethi kunye nomgaqo wokusebenza.
