I\u00f9l Luath mu Mhaighean<\/h1>\n

Tha magnetan aig gach \u00e0ite\u2014bhon dhorsan fridges gu turasan gaoithe\u2014ach d\u00e8 na stuthan a tha iad dha-r\u00ecribh, agus carson a bhios cuid de mheatailtean a\u2019 gluasad fhad \u2018s a bhios cuid eile chan eil?<\/p>\n

Tha magnetan air an d\u00e8anamh de stuthan a dh\u2019fhaodadh raon magnetach a chruthachadh, mar as trice meatailtean mar iarann, nicil, no cobalt, no alloyan a tha a\u2019 gabhail a-steach na h-eileamaidean seo. Bidh iad a\u2019 tarraing d\u00ecreach cuid de she\u00f2rsaichean meatailtean.<\/strong><\/p>\n

Ma dh\u2019fhaighnich thu riamh carson a bhios cl\u00f2-bhualadair a\u2019 cumail ri magnet fhad \u2018s nach eil r\u00ecng \u00f2ir a\u2019 d\u00e8anamh sin, briseadh s\u00ecos an sti\u00f9ireadh seo a h-uile c\u00e0il. Obraich mi le magnetan airson c\u00f2rr is 15 bliadhna, agus seallaidh mi dhut d\u00e8 a n\u00ecidh meatailt magnetach agus mar a dh\u2019fhaodas tu a chomharrachadh gu furasta.<\/p>\n

D\u00e8 a th\u2019 ann am magnet n\u00e0darra a chaidh a dh\u00e8anamh dheth?<\/h2>\n

Chan fheum magnetan a bhith air an d\u00e8anamh le l\u00e0imh gus a bhith ann\u2014tha cuid a\u2019 tachairt gu n\u00e0darra. Ach d\u00e8 a tha gan d\u00e8anamh s\u00f2nraichte?<\/p>\n

Tha magnetan n\u00e0darra air an d\u00e8anamh de magnetite, se\u00f2rsa de mheatailt ocsaidean iarainn. Tha e a\u2019 tachairt gu n\u00e0darra agus tha e le feartan magnetach air sg\u00e0th cho-\u00f2rdanachadh na h-iarainn aige.<\/strong><\/p>\n

D\u00e8 a th\u2019 ann am magnetite, agus carson a tha e magnetach?<\/h3>\n

Tha magnetite (Fe\u2083O\u2084) am measg nan stuthan magnetach n\u00e0darra as aithnichte. Tha e a\u2019 cruthachadh ann am brocagan igneous agus metamorphic agus chaidh a chleachdadh airson linntean, eadhon le se\u00f2ladairean sean ann am foirm lodestones.<\/p>\n

Tha magnetite magnetach air sg\u00e0th a structar criostal s\u00f2nraichte. Tha i a\u2019 gabhail a-steach d\u00e0 ions Fe\u00b2\u207a agus Fe\u00b3\u207a. Tha na h-eileanan gun ph\u00e0irt anns na h-iarraidean iarainn seo a\u2019 co-\u00f2rdanachadh ann an d\u00f2igh a chruthachadh raon magnetach f\u00e8in-ghluasadach.<\/p>\n

Chan eil a h-uile creag a tha a\u2019 gabhail a-steach iarann magnetach, ge-t\u00e0. Tha structar criostal agus r\u00e8iteachadh atomach cho cudromach ri na h-eileamaidean fh\u00e8in.<\/p>\n\n\n\n\n\n\n\n

Chan eil a h-uile magnet air an d\u00e8anamh mar an ceudna. D\u00e8 a thig a-steach do magnet gn\u00ecomhachais \u00e0bhaisteach?<\/p>\n

Tha a\u2019 mh\u00f2r-chuid de mhagnataichean air an d\u00e8anamh bho mheatailtean ferromagnetic mar iar, nickel, agus cobalt, no mheatailtean beinne ne\u00f2nach mar neodymium no samarium. Tha an taghadh de stuthan an urra ri cleachdadh a\u2019 mhagnatair.<\/strong><\/p>\n

A\u2019 coimeasachadh se\u00f2rsaichean agus stuthan cumanta de mhagnataichean<\/h3>\n

Tha iomadh se\u00f2rsa de mhagnatair ann, gach fear le \u201cgr\u00ectheidean\u201d no stuthan bunaiteach eadar-dhealaichte. Seo na h-\u00e0rd-chabhsairean as cumanta:<\/p>\n\n\n\n\n\n\n\n\n

Tha mi air obrachadh le na se\u00f2rsaichean seo uile. Is e na magnets neodymium an fheadhainn as fharsainge a chleachdar air sg\u00e0th an cumhachd, gu s\u00f2nraichte ann an meudan beaga. Ach ma tha do phr\u00f2iseact ag iarraidh resistant teas\u2014mar anns a\u2019 ch\u00e0r no an adhair-\u00e8adhair\u2014b\u2019 fhe\u00e0rr leam Samarium Cobalt.<\/p>\n

Tha gach gr\u00ectheid air a thaghadh gu faiceallach agus air a phr\u00f2iseasadh gus raointean magnetach a shuidheachadh r\u00e8 d\u00e8anamh. Gun a bhith a\u2019 d\u00e8anamh seo, cha bhi e comasach do iar gi\u00f9lan mar magnet.<\/p>\n
