✧ Pfupiso
Magineti eNIB anouya mumhando dzakasiyana, zvinoenderana nesimba remagetsi awo, kubva kuN35 (isina kusimba uye isingadhuri zvakanyanya) kusvika kuN52 (yakasimba, inodhura zvakanyanya uye inoputsika). Magineti eN52 akasimba ne50% kupfuura magineti eN35 (52/35 = 1.49). MuUS, zvakajairika kuwana magineti emhando yevatengi ari pakati peN40 neN42. Mukugadzirwa kwehuwandu, N35 inowanzo shandiswa kana saizi nehuremu zvisiri chinhu chikuru sezvo zvisingadhuri zvakanyanya. Kana saizi nehuremu zviri zvinhu zvakakosha, magineti epamusoro anowanzo shandiswa. Pane mutengo wemagineti emhando yepamusoro saka zvakajairika kuona magineti eN48 neN50 achishandiswa mukugadzirwa zvichienzaniswa neN52.
✧ Giredhi Rinosarudzwa Sei?
Magineti eNeodymium kana anozivikanwa zvakanyanya seNIB, NefeB kana super magnets ndiwo magineti akasimba uye anoshandiswa zvakanyanya pasi rese. Nemakemikari eNd2Fe14B, magineti eNeo ane chimiro chetetragonal crystalline uye anonyanya kuumbwa nezvinhu zveneodymium, Iron neBoron. Mumakore apfuura, magineti eNeodymium akatsiva mamwe marudzi ese emagineti anogara kwenguva refu kuti ashandiswe zvakanyanya mumota, electronics nezvimwe zvishandiso zvezuva nezuva. Nekuda kwekusiyana kwezvinodiwa zvemagnetism uye pull force pabasa rega rega, magineti eNeodymium anowanikwa zviri nyore mumagiredhi akasiyana. Magineti eNIB anoongororwa zvichienderana nezvinhu zvakagadzirwa nawo. Semutemo wekutanga, magiredhi akakwira, magineti achava akasimba.
Zita rekuti neodymium rinotanga ne'N' richiteverwa nenhamba ine manhamba maviri mukati memutsara we24 kusvika 52. Bhii 'N' mumagiredhi emagneti e-neo rinomiririra neodymium nepo nhamba dzinotevera dzichimiririra simba guru remagineti chaiwo rinoyerwa mu'Mega Gauss Oersteds (MGOe). Mgoe ndiyo chiratidzo chikuru chesimba remagineti e-neo pamwe nehuwandu hwesimba remagineti rinogadzirwa naro mukati memuchina chero upi zvawo kana kushandiswa. Kunyangwe huwandu hwepakutanga huchitanga neN24, magiredhi akaderera haachagadzirwa. Saizvozvowo, nepo simba guru rezvigadzirwa zveNIB richifungidzirwa kusvika kuN64 asi huwandu hwesimba rakadaro harisati raongororwa mukutengeserana uye N52 ndiyo giredhi repamusoro remagineti re-neo rinowaniswa nyore nyore nevatengi.
Mabhii ekuwedzera anotevera giredhi anoreva tembiricha yemagneti, kana kuti pamwe kusavapo kwayo. Tembiricha yakajairika ndeyeNil-MH-SH-UH-EH. Aya mabhii ekupedzisira anomiririra tembiricha yepamusoro yekushanda kwemagetsi kureva tembiricha yeCurie iyo magineti inogona kutsungirira isati yarasikirwa zvachose nemagnetism yayo. Kana magineti ikashandiswa kupfuura tembiricha yeCurie, mhedzisiro yacho ingave kurasikirwa nezvinobuda, kudzikira kwekushanda uye pakupedzisira demagnetization isingadzoreki.
Zvisinei, saizi chaiyo uye chimiro chemagineti e-neodymium zvine basa guru mukukwanisa kwayo kushanda zvinobudirira pakupisa kwakanyanya. Uyezve, chimwe chinhu chekurangarira ndechekuti simba remagineti emhando yepamusoro rinoenderana nenhamba, zvekuti N37 haina simba ne9% pane N46. Nzira yakavimbika yekuverenga giredhi chaiyo yemagineti e-neo ndeyekushandisa muchina wekuongorora graph we hysteresis.
AH Magnet ikambani inopa magineti asingawanzoonekwi, inova nyanzvi mukutsvaga, kugadzira, nekutumira kunze kwenyika magineti esimbi ane simba repamusoro-soro anonzi neodymium, ane magineti makumi mana nemanomwe emhando yepamusoro, kubva kuN33 kusvika ku35AH, uye GBD Series kubva ku48SH kusvika ku45AH. Kana uchifarira zvigadzirwa zvedu, ndapota taura nesu izvozvi!
