D\u00e8 an Magnet Seasmhach?<\/h1>\n

Tha magnets timcheall oirnn, ach a bheil thu riamh air stad a chur airson smaoineachadh mu dheidhinn d\u00e8 a n\u00ec magnet \u201cseasmhach\u201d? Leig \u00e0s sinn a mhilleadh s\u00ecos.<\/p>\n

Tha magnet seasmhach air a dh\u00e8anamh bho stuth a chaidh a magnetachadh agus faodaidh e a ghleusadh a raon magnetach gun fheum air dealan no st\u00f2r cumhachd eile.<\/strong><\/p>\n

Tha magnets a\u2019 cluich p\u00e0irt ann an a h-uile c\u00e0il bho mhotaran gu sensaran, agus faodaidh tu e\u00f2las a bhith agad air mar a tha iad ag obair gus do chuideachadh le bhith a\u2019 taghadh am fear cheart airson do phr\u00f2iseact a tha ri thighinn.<\/p>\n

 <\/p>\n

D\u00e8 an stuth a tha na magnet seasmhach?<\/h2>\n

Dh\u2019 fhaodadh magnets a bhith coltach ri draoidheachd, ach tha iad air an d\u00e8anamh bho stuthan f\u00ecor le feartan s\u00f2nraichte.<\/p>\n

Mar as trice tha magnets seasmhach air an d\u00e8anamh bho neodymium, samarium cobalt, alnico, no ferrite, gach fear a\u2019 tabhann feartan coileanta eadar-dhealaichte.<\/strong><\/p>\n

 <\/p>\n

Taghadh an stuth magnetach cheart<\/h3>\n

Tha magnets seasmhach eadar-dhealaichte air an dealbhadh airson feumalachdan s\u00f2nraichte. Mar eisimpleir:<\/p>\n\n\n\n\n\n\n\n\n
Stuth<\/th>\nFeartan<\/th>\nCleachdaidhean \u00e0bhaisteach<\/th>\n<\/tr>\n<\/thead>\n
Neodymium (NdFeB)<\/strong><\/span><\/a><\/td>\nNeart \u00e0rd, seasmhachd \u00ecosal te\u00f2thachd, buailteach do dh\u00f2rtadh<\/td>\nMothar \u00e0rd-choileanadh, dealanach<\/td>\n<\/tr>\n
Samarium Cobalt<\/strong><\/span><\/a><\/td>\nNeart math, seasmhachd te\u00f2thachd \u00e0rd, resistant do dh\u00f2rtadh<\/td>\nAerospace, uidheamachd meidigeach<\/td>\n<\/tr>\n
Alnico<\/span><\/strong><\/a><\/td>\nFoighidinn te\u00f2thachd \u00e0rd, neart meadhanach<\/td>\nSensaran, pickups giot\u00e0r<\/td>\n<\/tr>\n
Ferrite (Ceramic)<\/a><\/span><\/strong><\/td>\nGun chosgais, resistant do dh\u00f2rtadh, neart \u00ecosal<\/td>\nSpeakers, magnets frids<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Ann an e\u00f2las agam, tha m\u00f2ran luchd-d\u00e8iligidh gu bunaiteach a' faighinn ioma-mheatair neodymium airson an l\u00e0n chruasachd tarraing. Ach, \u00e0s d\u00e8idh dhuinn tuigse fhaighinn air te\u00f2thachd agus \u00e0rainneachd an tagraidh, bidh sinn gu tric a' tionndadh gu samarium cobalt airson seasamh an aghaidh te\u00f2thachd \u00e0rd no ferrite airson s\u00e0bhaladh cosgais.<\/p>\n

 <\/p>\n

Ciamar a tha thu a' faighinn a-mach ma tha magnet seasmhach?<\/h2>\n

Faodaidh e a bhith duilich a' faighinn a-mach, ach tha cuid de shoidheachan furasta ri faicinn.<\/p>\n

Tha magnet seasmhach ma tha e comasach dha tarraing stuthan ferromagnetic agus cumail suas magnetachd eadhon \u00e0s aonais st\u00f2r cumhachd taobh a-muigh.<\/strong><\/p>\n

 <\/p>\n

Deuchainn airson seasmhachd<\/h3>\n

Seo beagan dh\u00f2ighean a chleachdas mi nuair a tha mi a' measadh ma tha magnet seasmhach:<\/p>\n

1. Thoir s\u00f9il air a dh\u00f2igh-obrach<\/strong><\/h4>\n

Ma tha magnet comasach air peann-cl\u00f2 no n\u00e0l a chumail suas, tha e coltach gu bheil raon magnetach seasmhach aige.<\/p>\n

2. D\u00e8an sgr\u00f9dadh air cumhachd taobh a-muigh<\/strong><\/h4>\n

Feumaidh magnets sealach dealan no raon taobh a-muigh airson cumhachdachadh magnetachd. Chan eil seo riatanach airson magnets seasmhach. Thoir dheth inneal, agus ma tha am magnet fhathast ag obair, tha e seasmhach.<\/p>\n

3. Beachdaich air an stuth<\/strong><\/h4>\n
    \n
  • Neodymium agus Samarium Cobalt<\/strong>: An-c\u00f2mhnaidh seasmhach.<\/li>\n
  • Electromagnetan<\/strong>: Chan eil ach magnetach nuair a tha iad cumhachdach.<\/li>\n<\/ul>\n

    4. Faighnich don solaraiche<\/strong><\/h4>\n

    Ann am m' ghn\u00ecomhachas, bidh sinn an-c\u00f2mhnaidh a' suaicheantas magnets le am fear aca. Ma tha neach-d\u00e8iligidh m\u00ec-chinnteach, bidh sinn a' sgr\u00f9dadh an s\u00f2nrachadh stuth agus d\u00f2igh magnetization.<\/p>\n

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

    Tha magnetan seasmhach nan naoi-\u00e8ideadh gun chli\u00f9 a tha ann an teicne\u00f2las \u00f9r-nodha, a\u2019 toirt raon magnetach earbsach gun fheum air cumhachd. Bho innealan dachaigh gu teicne\u00f2las \u00e0ite, tha iad uile \u00e0ite.<\/p>","protected":false},"excerpt":{"rendered":"
