A bheil magnetan ag obair ann an \u00e0ite sam bith?<\/h1>\n

Faodaidh \u00e0ite a bhith m\u00f2r agus falamh, ach an robh fios agad nach eil feum aig magnetan air ad, tarraing, no eadhon conaltradh airson an obair a dh\u00e8anamh?<\/p>\n

Obairicheas magnetan gu foirfe ann an \u00e0ite oir tha raointean magnetach nach eil buailteach do tarraing no ad. Bidh iad a\u2019 fuireach seasmhach agus \u00e8ifeachdach eadhon ann an vacuum.<\/strong><\/p>\n

magnet ann an \u00e0ite<\/p><\/div>\n

Gu dearbh, tha magnetan a\u2019 cluich dreuchd chudromach ann an iomadh teicne\u00f2las \u00e0ite. Tha an s\u00ecmplidheachd agus earbsachd nan d\u00e0 chuid gan d\u00e8anamh riatanach airson smachd satallait, rannsachadh cosmic, agus miseanan \u00e0ite san \u00e0m ri teachd.<\/p>\n

<\/h2>\n

A bheil tarraing nas l\u00e0idire ann an \u00e0ite?<\/h2>\n

Tha daoine tric a\u2019 faighneachd ma tha magnetan ag obair gu diofar ann an \u00e0ite. An urrainn gun a bhith ann an tarraing no ad a dh\u00e8anamh nas l\u00e0idire?<\/p>\n

Chan atharraich tarraing fh\u00e8in ann an \u00e0ite. Tha neart magnet a\u2019 buntainn ri a stuth, chan e an \u00e0rainneachd.<\/strong><\/p>\n

A\u2019 briseadh s\u00ecos: \u00e0rainneachd vs. stuth<\/h3>\n

Nuair a bhios sinn a\u2019 bruidhinn mu neart magnet, tha sinn a\u2019 toirt iomradh air a raon magnetach, a th\u00e8id a thomhas ann an aonadan mar tesla no gauss. Tha an raon seo air a dhearbhadh le co-mheas, meud, agus dealbhadh a\u2019 magnet. Chan eil ad no tarraing ann an \u00e0ite, ach chan eil na factaran seo a\u2019 toirt buaidh air na h-urrasachd nan raointean magnetach.<\/p>\n\n\n\n\n\n\n\n\n

Tha neart magnet d\u00ecreach ag atharrachadh ma th\u00e8id an stuth a bhruiseadh thairis air a chuingeachadh obrach no a\u2019 fuarachadh gu \u00ecrean extreme mar te\u00f2thachd n\u00e0dair le n\u00ec ne\u00f2inean. Ann am poileasaidhean \u00e0ite, tha smachd te\u00f2thachd a\u2019 d\u00e8anamh cinnteach gu bheil magnetan ag obair gu h-\u00e0rd-\u00e8ifeachdach.<\/p>\n

Ann am m\u2019 ghn\u00ecomhachas, bidh sinn tric a\u2019 d\u00e8anamh deuchainn air magnetan neodymium agus SmCo airson luchd-d\u00e8iligidh ann an \u00e0ite-\u00e8ifeachd. Tha na stuthan seo air an taghadh oir tha iad a\u2019 cumail suas coileanadh ann an vacuum \u00e0ite. Ach, tha sinn an-c\u00f2mhnaidh a\u2019 moladh deuchainn fo chruinneachadh teirmeach gus d\u00e8anamh cinnteach de sheasmhachd.<\/p>\n

 <\/p>\n

Am bi magnet fhathast ag obair ann an \u00e0ite?<\/h2>\n

Chan fheum magnet tarraing no ad. Feumaidh e d\u00ecreach a stuth magnetach a bhith a\u2019 freagairt nan raointean.<\/p>\n

Obraichidh magnetan gu d\u00ecreach mar an aon d\u00f2igh anns a\u2019 chruinne-c\u00e8 ri air an Talamh. Bidh iad a\u2019 gineadh raointean magnetach ge bith c\u00e0ite a bheil iad.<\/strong><\/p>\n

Ciamar agus carson a tha e ag obair<\/h3>\n

\u00c8iridh raointean magnetach bho ghluasad electrons ann an atoms. Chan eil an cleachdadh ceimigeach seo an urra ri gr\u00e0nda no \u00e0rainneachd. Ge bith a bheil iad ann an orbit no air an talamh, bidh electrons magnetan a\u2019 cuairteachadh mar an ceudna, a\u2019 gineadh raon seasmhach.<\/p>\n

Seo ge\u00e0rr-chunntas air carson a tha magnetan ag obair anns a\u2019 chruinne-c\u00e8:<\/p>\n\n\n\n\n\n\n\n

Tha cuimhne agam air obair air pr\u00f2iseact le teachdaire a\u2019 dealbhadh siostaman smachd deuchainn satelite. Bha iad a\u2019 cleachdadh magnetorquers\u2014coileanan dealain-magnetach a tha a\u2019 conaltradh ris a\u2019 raon-magnetach na Talmhainn. Bidh am prionnsapal ag obair oir tha na raointean magnetach a\u2019 gi\u00f9lan gu cunbhalach, ge bith gun bhuaidh gr\u00e0nda.<\/p>\n

\"magnetorquers\"

Obraichidh magnetan anns an fhuachd na cruinne-c\u00e8?<\/h2>\n

Dh\u2019fhaodadh gum bi an fhuachd na cruinne-c\u00e8 coltach ri duilgheadas do mh\u00f2ran teicne\u00f2lasan. Ach chan e sin f\u00ecor airson magnetan.<\/p>\n

Seadh, obraichidh magnetan gu foirfe anns an fhuachd na cruinne-c\u00e8 oir chan fheum raointean magnetach adhar no conaltradh airson obrachadh.<\/strong><\/p>\n

Ciamar a tha magnetan ag obair ann an fhuachd?<\/h3>\n

Ann an fhuachd, chan eil adhar ann airson casg a chur air raointean magnetach, ach cuideachd chan eil eadar-theachd. Tha seo a\u2019 d\u00e8anamh magnetan earbsach airson seasmhachd satelite, siostaman se\u00f2ladh, agus lorg p\u00e0irtean cosmic.<\/p>\n

Biodh sinn a\u2019 sgr\u00f9dadh pr\u00ecomh ch\u00f9isean cleachdaidh:<\/p>\n

1. Smachd Sateilidh<\/strong><\/h4>\n

Bidh magnetorquers a\u2019 cleachdadh coileanan airson raointean magnetach a ghineadh. Bidh iad a\u2019 conaltradh ris a\u2019 raon-magnetach na Talmhainn, a\u2019 cur torque airson satelite a shuidheachadh. Is e siostam seasmhachd gun chumhachd a th\u2019 ann.<\/p>\n

2. Speactramar Magnetach Alpha (AMS-02)(d\u00e8an sgr\u00f9dadh air an blog seo bho Bunting Magnetics)<\/a><\/strong><\/h4>\n

Air a st\u00e0ladh air an ISS, bidh an AMS-02 a\u2019 cleachdadh magnet seasmhach l\u00e0idir airson rannsachadh air raidean cosmic. Tha seo a\u2019 cuideachadh le luchd-saidheans tuigse fhaighinn air antimatter agus dorchadas matter.<\/p>\n

3. Cuimhne Magnetach<\/strong><\/h4>\n

Anns na h-obraichean Apollo, bha cr\u00ecochan magnetach a\u2019 st\u00f2radh d\u00e0ta loidhneachaidh. Eadhon an-diugh, tha stuthan magnetach air an beachdachadh airson cuimhne ann an \u00e0ite oir tha iad gun bhuaidh bho radiation no call cumhachd.<\/p>\n

Seo cl\u00e0r a\u2019 ge\u00e0rr-chunntas cleachdadh \u00e0ite:<\/p>\n\n\n\n\n\n\n\n

Bha, aig \u00e0m co-obrachadh le neach-d\u00e8anaidh satelite sgudal, mhol sinn siostam glacadh magnetach. Bhiodh magnets a\u2019 tarraing ph\u00ecosan beaga sgudail, a\u2019 glanadh orbitan gun fheum air gaoth no armachd meacanaigeach.<\/p>\n

Co-dh\u00f9nadh<\/h2>\n

Tha magnets riatanach airson rannsachadh \u00e0ite. Tha an neo-eisimeileachd bho ghr\u00e0dh no adhair gan d\u00e8anamh earbsach airson iomadh tagradh, bho smachd satelite gu rannsachadh cosmic.<\/p>\n
