Wareegga Wareega ee Block Arc Ferrite Magnet Joogtada ah
Sharaxaada Alaabta
Ferrite Magnet (sidoo kale loo yaqaan magnet dhoobada) waa magnet joogto ah.
Waxay inta badan ku saleysan yihiin Strontium (SrFe2O3), oo lagu soo saaray wax lagu daro Strontium Carbonate si loo kordhiyo bandhigyada Barium ee duugoobay (BaFe2O3).
Xoogooda qasabka ah ee wanaagsan waxay ka timaadaa anisotropy crystal sare ee strontium iron oxide. Si kastaba ha ahaatee, qaybaha isotropic ayaa sidoo kale la soo saari karaa halkaas oo loo baahan yahay magnetization tiir fudud oo fudud.
Marka la eego sifooyinka korantada, iska caabinta ferrite aad ayuu uga weyn yahay kan birta iyo walxaha magnetic alloy, sidoo kale waxay leedahay sifooyin dielectric sare ah.
Astaamaha birlabeedka ee ferrite waxa kale oo ay muujinayaan ka bixitaan heer sare ah.
Ferrite ma aha mid firfircoon oo iska caabin sare leh oo ka soo horjeeda daxalka, asiidhka, cusbada, iyo saliidaha. Qaababka ugu caansan waa kuwa fudud, sida saxannada, baloogyada, dhululubada, giraangiraha, iyo qaansada.
Magnet-ka Ferrite waxaa caadi ahaan loo istcimaali jiray codsiyo kala duwan dhowrkii sano ee lasoo dhaafay, sida sameecadaha, matoorada, iyo koronto-dhaliyeyaasha.
