Zoo Ferrite Magnet Y10Y25Y33
Ferrite yog ferrimagnetic hlau oxide. Nyob rau hauv cov nqe lus ntawm cov khoom hluav taws xob, lub resistivity ntawm ferrite yog ntau loj dua li ntawm cov hlau los yog hlau alloy hlau, thiab nws kuj muaj ntau dua dielectric zog. Cov khoom sib nqus ntawm ferrites kuj qhia tau tias lawv muaj qhov permeability siab ntawm cov zaus siab. Yog li ntawd, ferrite tau dhau los ua cov khoom siv hlau nplaum uas tsis yog xim hlau uas siv dav hauv kev ua haujlwm siab zaus tsis muaj zog tam sim no. Vim tias lub zog sib nqus tsis tshua muaj nyob rau hauv chav tsev ntim ntawm ferrite, saturation magnetic induction (Bs) kuj tseem qis (feem ntau tsuas yog 1/3 ~ 1/5 ntawm cov hlau ntshiab), uas txwv tsis pub nws siv nyob rau hauv tsawg zaus yuav tsum muaj zog hlau nplaum ntau dua. ceev.
