Magnetan neodymium, ris an canar cuideachd magnetan Talamh-\u00d9r neo-\u00e0bhaisteach, tha iad air f\u00e0s gu math m\u00f2r-ch\u00f2rdte oir tha iad cho l\u00e0idir. Tha iad gu math nas l\u00e0idire na magnetan ferrite, eadhon ged a tha iad gu math beag. Ach tha cuid de bhuannachdan agus eas-bhuannachdan aig gach aon, mar sin tha iad nas fhe\u00e0rr airson diofar rudan.<\/p>\n

Se\u00f2rsan de Mhaighean<\/strong><\/span><\/h2>\n

Tha magnetan a' cruthachadh raon magnetach a tha a' tarraing cuid de mheatailtean. Faodaidh am fear sin tighinn bho magnet a thachras gu n\u00e0darra no bho magnet a chaidh a dh\u00e8anamh. Dh\u00e0 de na magnetan as cumanta a tha air an d\u00e8anamh le daoine 's e ferrite agus neodymium. Tha iad uile air an gairm \"seasmhach\" oir bheir iad suas mar magnetan gu br\u00e0th mura bheil iad air an sgrios no air an demagnetachadh. Ach tha magnetan neodymium nas l\u00e0idire na magnetan ferrite, mar sin tha iad air an cleachdadh ann an iomadh rud an-diugh.<\/p>\n

Tha maighstirean ferrite air a bhith ann bho na 1950an agus tha iad fhathast air an cleachdadh gu m\u00f2r an-diugh oir tha iad saor. Tha iad air an d\u00e8anamh le bhith a\u2019 measgachadh stuthan ferrite leithid ferrite strontium no barium. Faodaidh tu an d\u00e8anamh ann an cruth sam bith a tha thu ag iarraidh. Tha iad cuideachd gu math an aghaidh meirge, mar sin chan fheum iad c\u00f2mhdach sam bith ma th\u00e8id an cleachdadh ann an \u00e0rainneachd fliuch. Chan eil iad a\u2019 call an magnetachd cho m\u00f2r aig te\u00f2thachd \u00e0rd cuideachd. Ach is e an duilgheadas m\u00f2r le maighstirean ferrite nach eil iad gu math l\u00e0idir.<\/p>\n

Magnetan Neodymium<\/a>L\u00e0idir, ach gu math daor<\/strong><\/span><\/h2>\n

\"\"<\/p>\n

Chaidh magnetan neodymium a leasachadh anns na 1970an. Tha iad nam p\u00e0irt den teaghlach magnetan Talmhainn neo-\u00e0bhaisteach agus tha iad gu math l\u00e0idir. Tha iad nas daoire na magnetan ferrite, ach tha iad gu math l\u00e0idir. Tha na magnetan neodymium as l\u00e0idire (mar N52) 6.5 tursan nas l\u00e0idire na na magnetan ferrite as fhe\u00e0rr (mar C8). Mar sin, tha magnetan neodymium air an cleachdadh far a bheil feum agad air magnet beag le t\u00f2rr tarraing. Gheibh thu iad ann am motaran, dr\u00e0ibhearan cruaidh, agus electronics \u00e0rd-ch\u00e0ileachd.<\/p>\n

Ach tha cuid de dhuilgheadasan aig magnetan neodymium. Tha iad nas dualtaiche do corrachadh na magnetan ferrite, mar sin feumaidh iad c\u00f2mhdach d\u00econach sam bith orra. Dh\u2019fhaodadh sin a bhith nickel no epoxy. Feumaidh tu cuideachd a bhith faiceallach leotha oir tha iad briste agus faodaidh iad briseadh ma th\u00e8id iad a bhualadh ri ch\u00e8ile. Agus chan eil iad d\u00e8idheil air te\u00f2thachd \u00e0rd. Bidh a\u2019 mh\u00f2r-chuid de chlasan de magnetan neodymium a\u2019 call an magnetachd ma thig iad gu te\u00f2thachd ro \u00e0rd.<\/p>\n

Magnet Ferrite vs Neodymium <\/strong><\/span><\/h2>\n

Nuair a tha thu a' coimeasachadh magnetan ferrite ri magnetan neodymium, seo na rudan a dh' fheumas tu beachdachadh orra:<\/p>\n

Neart Magnetach (BHmax): Tha maighstirean Neodymium fada nas l\u00e0idire. Tha am maighstir neodymium as l\u00e0idire (N52) mu 6.5 tursan nas l\u00e0idire na am maighstir ferrite as l\u00e0idire (C8).<\/p>\n

F\u00f2cas f\u00f2ce: Tha magnetan neodymium nas seasmhaiche na magnetan ferrite ann an aghaidh demagnetization. Faodaidh magnet neodymium l\u00e0idir demagnetize magnet ferrite.<\/p>\n

Te\u00f2thachd Obrach as \u00c0irde: Faodaidh maighstirean ferrite d\u00e8iligeadh ri teothachd nas \u00e0irde (gu suas ri 250\u00b0C) gun a bhith a\u2019 call m\u00f2ran den magnetachd aca. Tha teothachdan obrach as \u00e0irde nas \u00ecsle aig maighstirean neodymium, ach tha cuid de \u00ecrean teothachd \u00e0rd ann a dh\u2019fhaodas d\u00e8iligeadh ri suas ri 220\u00b0C.<\/p>\n

Resistance creimeadh: Tha magnets ferrite nas fhe\u00e0rr ann a bhith a\u2019 cur an aghaidh creimeadh agus mar as trice chan fheum iad c\u00f2mhdach sam bith. Feumaidh magnets neodymium c\u00f2mhdach orra (nicil, epoxy, plastaig) oir tha iad air an d\u00e8anamh sa mh\u00f2r-chuid de iarann.<\/p>\n

 <\/p>\n

D\u00e8 a chleachdadh cuin: Cosgais an aghaidh Cumhachd<\/strong><\/span><\/h2>\n

Nuair a thig e gu cosgais, tha magnetan ferrite nas saoire. Mar sin ma tha thu a' feuchainn ri airgead a sh\u00e0bhaladh, tha magnetan ferrite na dh\u00f2igh air a dhol. Ach ma ch\u00ec thu d\u00e8 cho m\u00f2r na h-\u00e8ifeachd tarraing a tha thu a' faighinn gach dollar, tha magnetan neodymium gu h-\u00e0bhaisteach a' toirt barrachd \u00e8ifeachd tarraing airson do chuid airgid. Mar eisimpleir, dh\u2019fhaodadh magnet neodymium a bhith aig a bheil \u00e8ifeachd tarraing de 6.44 punnd a chosg thu $0.99. Dh\u2019fhaodadh magnet ferrite a bhith d\u00ecreach le \u00e8ifeachd tarraing de 1 phund agus a chosg thu $0.34. Mar sin, nuair a ch\u00ec thu na neart gach dollar, tha magnetan neodymium nas fhe\u00e0rr.<\/p>\n

\u00a0<\/strong><\/p>\n

Seasmhachd agus Fad-beatha<\/strong><\/span><\/h2>\n

Bidh magnetan Neodymium a' cumail an magnetachd airson \u00f9ine mh\u00f2r. Mar a bhios tu gan teasachadh ro mh\u00f2r no gan briseadh, cha leig iad ach mu 1% den magnetachd aca gach deichead. Tha magnetan Ferrite nas dualtaiche call an magnetachd aca thar \u00f9ine agus dh\u2019fhaodadh gum bi feum air an ath-magnetachadh.<\/p>\n

 <\/p>\n

Carson a thaghas tu magnetan Neodymium?<\/strong><\/span><\/h2>\n

Tha magnetan ferrite saor agus ag obair gu math airson m\u00f2ran rudan. Ach ma tha feum agad air rudeigin a tha gu math l\u00e0idir, gu math beag, agus a mhaireas fad \u00f9ine, feumaidh tu magnet neodymium. Is e magnetan neodymium an adhbhar gum faod sinn rudan cho beag agus \u00e8ifeachdach a dh\u00e8anamh an-diugh. Is e an taobh droch na tha iad nas daoire agus feumaidh iad c\u00f2mhdach orra. Ach tha an taobh math na tha iad gu math l\u00e0idir agus mairidh iad gu s\u00ecorraidh mura h-ith iad ro theth no briseadh iad. Mar sin ma tha thu a' cleachdadh magnetan ferrite agus ag iarraidh faighinn a-mach ma dh\u2019fhaodadh tu magnet neodymium a chleachdadh an \u00e0ite, bruidhinn ri innleadair. Dh\u2019fhaodadh iad do chuideachadh le bhith a\u2019 faighinn coileanadh nas fhe\u00e0rr \u00e0s do thoraidhean.<\/p>","protected":false},"excerpt":{"rendered":"
