Hordhac Isotropic iyo Anisotropic Ferrite

Hordhaca Sawirka Isotropic iyo Anisotropic Ferrite

Sharaxaad Gaaban:

Magnet ferrite waa bir oksaydh bir ah, inta badan waxa laga sameeyaa isku dhafka birta oksaydhka iyo biraha kale ee oksaydhka ah (sida nikkel, zinc, manganese, iwm.).Waa bir oxide nooca bir ah oo aad u adkeysi badan u leh daxalka qiimahooduna jaban yahay, laakiin guud ahaan aan lahayn goob bir ah oo xoog badan.Magnet-ka Ferrite waxaa badanaa loo isticmaalaa qalabyo badan oo guriga ah, qalabka elegtarooniga ah iyo qaybaha gudbinta baabuurta.Waxa kale oo loo isticmaalaa in lagu sameeyo qalabka korontada, matoorada iyo kuwa ku hadla.

Isotropic iyo ferrite anisotropic waa laba nooc oo kala duwan oo ah qalabka magnetic.Qalabka ferrite ee Isotropic waxay leeyihiin sifooyin birlab ah oo isku mid ah dhammaan jihooyinka, taasoo la micno ah in hantidoodu ay isku mid yihiin iyadoon loo eegin jihada magnetic field loo isticmaalo.Waxaa loo adeegsadaa codsiyada u baahan magnet-ku inuu yeesho awood isku mid ah oo ku saabsan dhammaan jihooyinka.Qalabka ferrite ee anisotropic, dhanka kale, waxay leeyihiin sifooyin magnetic kala duwan oo jihooyin kala duwan ah.Waxay leeyihiin dhidibkii magnetization-ka ee la door biday waxayna muujinayaan magnetism ka xoog badan dhidibkaan marka loo eego jihooyinka kale.Anisotropic ferrites waxaa sida caadiga ah loo isticmaalaa codsiyada u baahan dhul magnetic jihada xooggan, sida dareemayaasha magnetic iyo anteenooyinka.Ferrite Isotropic iyo anisotropic waxaa si weyn loogu isticmaalaa codsiyada warshadaha iyo macaamiisha kala duwan sababtoo ah sifooyinkooda magnetic iyo qiimo jaban.

Ma kala garan kartid muuqaalka.Isotropic-ka marka la cadaadiyo (cadaadis qallalan ama riixaya qoyan), waxaa jira beer birlab ah, si markaa dhidibka fudud ee magnetization ee budada magnetic loo siman yahay.Anisotropic-ku wuxuu qiyaastii 3 jeer ka badan yahay kan isotropic.Isotropic-ku wuu ka fudud yahay anisotropic marka la samaynayo.Sidaa darteed, qiimaha qalabka iyo qiimaha halbeegga ee magnets isotropic waa ka jaban yahay, laakiin xoogga magnetic aad ayuu u daciifsan yahay.

Faa'iidadayada:
1. Waxqabadka qiimaha sare leh: Waxaan leenahay tignoolajiyada horumarsan iyo qalabka, alaabooyin iyo adeegyo tayo sare leh, iyo qiimo macquul ah.Gaar ahaan tayada sidoo kale waxaa aqoonsaday macaamiishu waxayna ka heleen ammaan wadajir ah macaamiisha.
2. Deganaanshiyo sare: Waxaan qaadanay tignoolajiyada sare iyo qalabka, iyo alaabtu waxay muujinaysaa xasillooni aad u sareysa inta lagu jiro isticmaalka, kaas oo buuxin kara shuruudaha macaamiisha ee xasilloonida sare.
3. Codsiga ballaaran: Alaabadayada waxaa si ballaaran loogu isticmaali karaa qalabka elektiroonigga ah iyo electro-acoustic, isgaarsiinta, caafimaadka, baabuurta iyo beeraha kale, waxayna siiyan macaamiisha xalal dhamaystiran, kuwaas oo loo habeyn karo si waafaqsan baahida macaamiisha, si ay u bixiyaan qorshaha ugu fiican. .
4. Saxnimada sare: Waxaan qaadaneynaa tignoolajiyada wax soo saarka sare iyo qalabka si loo hubiyo saxnaanta sare ee alaabta.
5. Bixinta degdega ah: Waxaan leenahay habka wax soo saarka dhamaystiran iyo nidaamka saadka, kaas oo si degdeg ah u gaarsiin kara si loo daboolo baahiyaha degdega ah ee macaamiisha, waxaanan ku siin karnaa taageero farsamo oo xirfad leh iyo adeegga iibka ka dib.Xubnaha kooxdu waxay leeyihiin khibrad warshadeed qani ah waxayna siin karaan macaamiisha xalal iyo adeegyo la beegsaday.
