An Magnet Seasmhach as L\u00e0idire \u2013 Magnet Neodymium<\/h1>\n\n

Tha magnetan an \u00e0ite sam bith, ach chan eil m\u00f2ran dhaoine e\u00f2lach air d\u00e8 am fear a tha gu f\u00ecrinneach a\u2019 sti\u00f9ireadh a\u2019 phaca ann an neart.<\/p>\n

Is iad magnetan neodymium na magnetan seasmhach as l\u00e0idire a tha rim faighinn an-diugh, a\u2019 d\u00e8anamh nas fhe\u00e0rr na se\u00f2rsaichean eile uile ann an neart magnetach agus d\u00f9mhlachd l\u00f9th.<\/strong><\/p>\n

Bhuail magnetan neodymium air mar a smaoinicheas sinn mu neart magnetach. Tha an cumhachd iongantach falaichte anns an tomhas beag aca. Leig dhuinn sgr\u00f9dadh a dh\u00e8anamh air d\u00e8 a tha gan d\u00e8anamh cho \u00e8ifeachdach\u2014agus carson a tha iad gun choimeas air a\u2019 mhargaidh.<\/p>\n

D\u00e8 an neart magnet as \u00e0irde?<\/h2>\n

Bidh a\u2019 mh\u00f2r-chuid a\u2019 smaoineachadh gum feum magnetan m\u00f2ra a bhith as l\u00e0idire. Chan eil sin f\u00ecor an-c\u00f2mhnaidh.<\/p>\n

Tha an neart magnet as \u00e0irde a\u2019 tighinn bho magnetan neodymium, gu s\u00f2nraichte an fheadhainn le \u00ecrean mar N52, a tha a\u2019 toirt seachad toraidhean l\u00f9th thairis air 50 MGOe. Tha N54 agus N55 againn cuideachd. <\/strong><\/p>\n

A\u2019 tuigsinn neart magnet ann an teirmean f\u00ecor<\/h3>\n

Gus neart magnet a thuigsinn, bidh mi an-c\u00f2mhnaidh a\u2019 coimhead air an toradh l\u00f9th as \u00e0irde, no (BH)max. Tha an luach seo a\u2019 sealltainn dhuinn cia mheud l\u00f9th magnetach as urrainn do stuth a st\u00f2radh. Tha luachan nas \u00e0irde a\u2019 ciallachadh magnetan nas l\u00e0idire. Mar as trice tha magnetan neodymium eadar 30 agus 55 MGOe, a r\u00e8ir an \u00ecre.<\/p>\n

Is e N55 an \u00ecre as l\u00e0idire a thathar a\u2019 cleachdadh gu cumanta an-diugh. Tha cuid de lannan-lann air \u00ecrean nas \u00e0irde a chruthachadh, ach chan eil iad ri fhaighinn gu farsaing air sg\u00e0th cosgais agus draghan mu sheasmhachd.<\/p>\n

Tha cuid de mhaighstirean coltach ri ch\u00e8ile ach bidh iad ag obair gu gu math eadar-dhealaichte.<\/p>\n

Tha neart maighstir an urra ri co-dh\u00e8anamh stuth, structar a-staigh, pr\u00f2iseas saothrachaidh, agus \u00ecre.<\/strong><\/p>\n

An saidheans air c\u00f9l neart maighstir<\/h3>\n

Tha ceithir factaran cudromach a tha a\u2019 toirt buaidh air neart magnetach:<\/p>\n

1. Co-dh\u00e8anamh<\/h4>\n

Tha maighstirean neodymium air an d\u00e8anamh bho mheasgachadh de neodymium, iarann, agus boron (Nd\u2082Fe\u2081\u2084B). Cruthaichidh an cothlamadh seo raon magnetach gu math d\u00f9mhail. Bidh maighstirean ferrite, air an l\u00e0imh eile, a\u2019 cleachdadh strontium no barium agus a\u2019 tabhann m\u00f2ran nas lugha de neart.<\/p>\n

2. Structar criostail<\/h4>\n

Tha d\u00f2igh a tha na atoman a\u2019 r\u00e8iteachadh taobh a-staigh a\u2019 mhaighstir cudromach. Tha structar criostail tetragonal aig maighstirean neodymium a tha a\u2019 toirt taic do magnetachadh \u00e0rd. Bidh an structar seo a\u2019 cuideachadh le bhith a\u2019 glaodhadh a-steach don raon magnetach agus a\u2019 cur an aghaidh d\u00ec-mhaighstireachd.<\/p>\n

\"Structar

3. \u00ccre<\/h4>\n

Tha an \u00ecre (mar N35, N42, N55) a\u2019 sealltainn cho l\u00e0idir \u2018s a tha am maighstir. Tha barrachd l\u00f9th magnetach gach aonad tomhas aig \u00ecrean nas \u00e0irde. Ach tha maighstirean le \u00ecre nas \u00e0irde cuideachd nas cruaidhe agus nas mothachail air teas.<\/p>\n

4. C\u00e0ileachd saothrachaidh<\/h4>\n

Bidh d\u00f2ighean sinteir, br\u00f9thadh, agus c\u00f2mhdach uile a\u2019 toirt buaidh air mar a bhios am maighstir deireannach ag obair. Ma tha am pr\u00f2iseas saothrachaidh neo-chunbhalach, dh\u2019fhaodadh am maighstir a bhith fo choileanadh no a dhol \u00e0 bith gu luath.<\/p>\n

D\u00e8 an magnet as cumhachdaiche?<\/h2>\n

Chan eil na maighstirean uile air an cruthachadh co-ionann\u2014eadhon taobh a-staigh an aon se\u00f2rsa.<\/p>\n

Is iad maighstirean neodymium an fheadhainn as cumhachdaiche, agus am measg annta, tha \u00ecre N55 a\u2019 tabhann an coileanadh magnetach as \u00e0irde.<\/strong><\/p>\n

A\u2019 d\u00e8anamh coimeas eadar \u00ecrean neodymium<\/h3>\n

Leig dhomh roinn beagan bho mo obair l\u00e0itheil. Nuair a bhios luchd-ceannach ag iarraidh \u201can magnet as l\u00e0idire,\u201d bidh mi mar as trice a\u2019 sealltainn dhaibh maighstirean neodymium N55. Bidh iad a\u2019 l\u00ecbhrigeadh an fheachd tarraing as \u00e0irde anns an tomhas as lugha.<\/p>\n

Ach chan eil N55 as fhe\u00e0rr airson a h-uile cleachdadh. Faodaidh e sg\u00e0ineadh gu furasta agus bidh e a\u2019 call neart ann an te\u00f2thachd \u00e0rd. Mar sin, bidh mi tric a\u2019 moladh N42 no N48 airson cleachdaidhean a-muigh no motaran.<\/p>\n\n\n\n\n\n\n\n

Ma tha neart na amas agad a-mh\u00e0in, tagh N55. Ach ma dh\u2019 fheumas tu cothromachadh, is e N42 an roghainn mhath.<\/p>\n

Carson a tha magnetan talamh tearc cho cumhachdaiche?<\/h2>\n

Chan eil a\u2019 mh\u00f2r-chuid de dhaoine e\u00f2lach carson a tha maighstirean talmhainn tearc nas fhe\u00e0rr na feadhainn eile cho furasta.<\/p>\n

Bidh maighstirean talmhainn tearc a\u2019 cleachdadh eileamaidean mar neodymium agus samarium, aig a bheil dealanan neo-ch\u00e0irdeil a tha a\u2019 cruthachadh raointean magnetach l\u00e0idir.<\/strong><\/p>\n

Tha an d\u00ecomhaireachd anns an gi\u00f9lan atamach<\/h3>\n

Tha structaran dealanach s\u00f2nraichte aig eileamaidean talmhainn tearc, gu s\u00f2nraichte neodymium. Tha m\u00f2ran dealanan neo-ch\u00e0irdeil aca anns an sgiath a-muigh. Leigidh seo le raointean magnetach gu math l\u00e0idir a bhith ann. Nuair a tha iad air an r\u00e8iteachadh, cruthaichidh na raointean sin sruth magnetach \u00e0rd.<\/p>\n

Tha d\u00e0 she\u00f2rsa pr\u00ecomh de mhaighstirean talmhainn tearc:<\/p>\n

    Chunnaic mi m\u00f2ran ghn\u00ecomhachasan a\u2019 gluasad gu maighstirean talmhainn tearc gus meud a lughdachadh agus \u00e8ifeachdas a mheudachadh, bho motaran gu innealan meidigeach.<\/p>\n

    Tha maighstirean Neodymium gun choimeas ann an neart, gan d\u00e8anamh nan roghainn as fhe\u00e0rr airson tagraidhean maighstireachd \u00e0rd-choileanadh.<\/p>","protected":false},"excerpt":{"rendered":"
