Incamake
Imashini za NIB ziza mubyiciro bitandukanye, bihuye nimbaraga zumurima wabo wa magneti, kuva kuri N35 (intege nke kandi zihenze cyane) kugeza kuri N52 (ikomeye, ihenze cyane kandi yoroheje). Imashini ya N52 ikomera hafi 50% kuruta N35 (52/35 = 1.49). Muri Amerika, birasanzwe kubona urwego rwabaguzi murwego rwa N40 kugeza N42. Mu musaruro mwinshi, N35 ikoreshwa kenshi niba ingano nuburemere bititabwaho cyane kuko bihenze. Niba ingano n'uburemere ari ibintu bikomeye, amanota yo hejuru arakoreshwa. Hano hari premium ku giciro cya magneti yo mu rwego rwo hejuru kuburyo bikunze kugaragara kubona magneti N48 na N50 zikoreshwa mubikorwa na N52.

Imashini ya Neodymium cyangwa izwi cyane nka NIB, NefeB cyangwa super magneti nizo zikomeye kandi zikoreshwa cyane mubucuruzi buboneka kwisi yose. Hamwe nimiti ya Nd2Fe14B, neo magnet ifite imiterere ya tetragonal kristaline kandi igizwe ahanini nibintu bya neodymium, Iron na Boron. Mu myaka yashize, neodymium magnet yasimbuye neza ubundi bwoko bwose bwa magnesi zihoraho kugirango zikoreshwe cyane muri moteri, ibikoresho bya elegitoroniki nibindi bikoresho bitandukanye bya buri munsi byubuzima. Bitewe no gutandukanya ibisabwa bya magnetisme no gukurura imbaraga kuri buri gikorwa, magnesi ya neodymium iraboneka byoroshye mubyiciro bitandukanye. Magnet ya NIB itondekanya ukurikije ibikoresho bigizwe. Nka tegeko shingiro, urwego rwo hejuru amanota, imbaraga zizaba zikomeye.
Amazina ya neodymium ahora atangirana na 'N' agakurikirwa numubare wimibare ibiri murukurikirane rwa 24 kugeza 52. Inyuguti 'N' mumanota ya neo magneti igereranya neodymium mugihe imibare ikurikira yerekana ibicuruzwa bitanga ingufu zidasanzwe. magnet apimirwa muri 'Mega Gauss Oersteds (MGOe). Mgoe nikimenyetso cyibanze cyimbaraga za magneti yihariye kimwe nuburinganire bwumurima wa magneti wabyaye mubikoresho cyangwa porogaramu. Nubwo urwego rwumwimerere rutangirana na N24 ariko, amanota yo hasi ntagikora. Mu buryo nk'ubwo, mugihe ingufu zishoboka zose zishoboka za NIB ziteganijwe kugera kuri N64 nyamara urwego rwingufu rwo hejuru ntirwigeze rugenzurwa mubucuruzi kandi N52 nicyiciro cyo hejuru cya neo cyoroshye kuboneka kubakoresha.
Inyuguti zose zinyongera zikurikira urwego zerekana ubushyuhe bwubushyuhe bwa magneti, cyangwa ahari kubura. Ibipimo by'ubushyuhe bisanzwe ni Nil-MH-SH-UH-EH. Izi nyuguti zanyuma zerekana ubushyuhe ntarengwa bwo gukora ni ukuvuga ubushyuhe bwa Curie rukuruzi ishobora kwihanganira mbere yuko itakaza burundu magnetism. Iyo rukuruzi ikozwe hejuru yubushyuhe bwa Curie, igisubizo cyaba igihombo cyumusaruro, kugabanya umusaruro kandi amaherezo demagnetisation idasubirwaho.
Nyamara, ingano yumubiri nuburyo bwa magneti ya neodymium nayo igira uruhare runini mubushobozi bwayo bwo gukora neza mubushyuhe bwo hejuru. Byongeye kandi, ikindi kintu ugomba kwibuka nuko imbaraga za magnet nziza nziza zingana numubare, kuburyo N37 ifite intege nke 9% gusa kuruta N46. Inzira yizewe yo kubara igipimo nyacyo cya neo magnet ni mugukoresha imashini igerageza hystereze.
AH Magnet ni isi idasanzwe itanga magneti yihariye mubushakashatsi, guteza imbere, gukora no kohereza ibicuruzwa mu mahanga cyane bya neodymium fer boron magnet, amanota 47 ya magneti asanzwe ya neodymium, kuva N33 kugeza 35AH, na GBD Series kuva 48SH kugeza 45AH irahari. Niba ushimishijwe nibicuruzwa byacu, nyamuneka twandikire nonaha!
