Anzake omwe amawadziwa bwino maginito amadziwa kuti maginito a iron boron amadziwika pamsika wazinthu zamaginito ngati zinthu zogwira ntchito kwambiri komanso zotsika mtengo. Amapangidwa kuti agwiritsidwe ntchito m'njira zosiyanasiyanamafakitale apamwambas, kuphatikizapo chitetezo cha dziko ndi asilikali, teknoloji yamagetsi, ndi zipangizo zamankhwala, magalimoto, zipangizo zamagetsi, zipangizo zamagetsi, ndi zina. Akagwiritsidwa ntchito kwambiri, zimakhala zosavuta kuzindikira zovuta. Pakati pa izi, demagnetization wa chitsulo-boron maginito amphamvu mu zoikamo kutentha kwambiri walandira chidwi kwambiri.Choyamba, tiyenera kumvetsa chifukwa NeFeB demagnetizes mu mapangidwe kutentha.
Maonekedwe a Ne iron boron amatsimikizira chifukwa chake amachotsa maginito m'malo otentha kwambiri. Nthawi zambiri, maginito amatha kupanga mphamvu ya maginito chifukwa ma elekitironi omwe amanyamulidwa ndi zinthuzo amazungulira ma atomu mbali ina yake, zomwe zimapangitsa kuti pakhale mphamvu yamaginito yomwe imakhudza nthawi yomweyo pazinthu zolumikizidwa. Komabe, kutentha kwapadera kuyenera kukwaniritsidwa kuti ma elekitironi azizungulira ma atomu mwanjira inayake. Kulekerera kwa kutentha kumasiyana pakati pa zipangizo zamaginito. Kutentha kukakwera kwambiri, ma elekitironi amachoka panjira yawo yoyamba, zomwe zimabweretsa chisokonezo. Izi Panthawiyi, mphamvu ya maginito ya m'deralo idzasokonekera, zomwe zimabweretsademagnetization.Kutentha kwa demagnetization kwa boron chitsulo chachitsulo nthawi zambiri kumatsimikiziridwa ndi kapangidwe kake, mphamvu ya maginito, ndi mbiri yochizira kutentha. Kutentha kwa demagnetization kwa boron yachitsulo chagolide nthawi zambiri kumakhala pakati pa 150 ndi 300 digiri Celsius (302 ndi 572 madigiri Fahrenheit). Mkati mwa kutentha uku, mawonekedwe a ferromagnetic amawonongeka pang'onopang'ono mpaka kutayika kwathunthu.
Mayankho angapo opambana a NeFeB maginito apamwamba kutentha demagnetization:
Choyamba, musawotche mankhwala a maginito a NeFeB. Yang'anirani kwambiri kutentha kwake koopsa. Kutentha kofunikira kwa maginito a NeFeB kumakhala pafupifupi madigiri 80 Celsius (madigiri 176 Fahrenheit). Sinthani malo ake ogwirira ntchito posachedwa. Demagnetization imatha kuchepetsedwa pokweza kutentha.
Chachiwiri, ndikuyamba ndi ukadaulo wowongolera magwiridwe antchito azinthu zogwiritsa ntchito maginito a hairpin kuti athe kukhala ndi mawonekedwe ofunda komanso kuti asatengeke ndi chilengedwe.
Chachitatu, ndi chinthu chomwecho maginito mphamvu mankhwala, mukhoza kusankhazida zokakamiza kwambiri. Ngati izo zikulephera, mungathe kungopereka pang'ono mphamvu ya maginito mankhwala kuti mukwaniritse kukakamiza kwakukulu.
PS: Chilichonse chili ndi makhalidwe osiyanasiyana, choncho sankhani yoyenera komanso yachuma, ndipo ganizirani mosamala popanga, apo ayi zidzatayika!
Tiyerekeze kuti mulinso ndi chidwi ndi izi: Momwe mungachepetsere kapena kupewa kutulutsa maginito kwamafuta ndi okosijeni wa iron boron, zomwe zimapangitsa Kuchepetsa kukakamiza?
Yankho: Ili ndi vuto ndi demagnetization yamafuta. Ndizovutadi kuzilamulira. Samalani kuwongolera kutentha, nthawi ndi digiri ya vacuum panthawi ya demagnetization.
Kodi maginito a iron-boron adzagwedezeka ndikukhala opanda maginito pati?
Maginito a maginito okhazikika sadzakhala opanda maginito chifukwa cha kugwedezeka kwafupipafupi, ndipo galimoto yothamanga kwambiri sichidzachotsedwa ngakhale pamene liwiro likufika pa 60,000 rpm.
Zomwe zili pamwambapa za maginito zidapangidwa ndikugawidwa ndi Hangzhou Magnet Power Technology Co., Ltd. Ngati muli ndi mafunso ena aliwonse a maginito, chonde omasukafunsani makasitomala pa intaneti!
