Maighneatan Neodymium<\/span><\/a> air an cleachdadh ann an iomadh gn\u00ecomhachas eadar-dhealaichte oir tha iad l\u00e0idir, beag, agus saor. Ach tha e cudromach d\u00e8anamh cinnteach gu bheil iad nan deagh magnets airson na stuthan a n\u00ec thu. Tha beagan rudan ann a dh\u2019 fheumas tu sgr\u00f9dadh a dh\u00e8anamh gus d\u00e8anamh cinnteach gu bheil magnet neodymium math agad. Feumaidh tu coimhead air feartan coileanaidh, an d\u00f2igh anns a bheil iad a\u2019 coimhead, agus mar a tha iad air an d\u00e8anamh.<\/strong><\/p>\n

Coileanadh<\/span><\/strong><\/h2>\n

Is e a\u2019 chiad rud a tha thu airson sgr\u00f9dadh a dh\u00e8anamh air coileanadh a\u2019 magnet neodymium. Tha t\u00f2rr \u00ecrean eadar-dhealaichte de magnets neodymium ann. Tha \u00ecrean a\u2019 dol bho N35 gu N52. Mar as \u00e0irde an \u00e0ireamh, is ann as l\u00e0idire a tha am magnet agus as daoire a tha e. Ach, d\u00ecreach air sg\u00e0th gu bheil magnet \u00e0rd-\u00ecre agad chan eil sin a\u2019 ciallachadh gu bheil e nas fhe\u00e0rr airson an tagraidh agad. Feumaidh tu fios a bhith agad d\u00e8 a tha thu airson gum d\u00e8an am magnet. Ma tha feum agad air magnet airson obrachadh ann an \u00e0rainneachd \u00e0rd-te\u00f2thachd, is d\u00f2cha gum feum thu magnet a tha comasach air coileanadh nas fhe\u00e0rr aig te\u00f2thachdan \u00e0rda. Ma tha magnet agad a tha gu bhith air a chleachdadh ann an inneal beag dealanach, is d\u00f2cha gum feum thu magnet a tha nas lugha agus aig a bheil raon magnetach nas l\u00e0idire.<\/strong><\/p>\n

Is e aon deuchainn as urrainn dhut a dh\u00e8anamh meatair Gauss a chleachdadh gus neart a\u2019 magnet a thomhas. D\u00e8an coimeas eadar an neart a thomhais thu leis an d\u00e0ta sampall \u00e0bhaisteach a thug neach-d\u00e8anamh a\u2019 magnet seachad.<\/strong><\/p>\n

Is e an ath rud a tha thu airson sgr\u00f9dadh a dh\u00e8anamh air d\u00e8anamh stuthan a\u2019 magnet. Tha an co-mheas de neodymium, iarann, agus boron anns a\u2019 magnet a\u2019 dearbhadh neart an raoin magnetach aige. Bheir an d\u00f2igh anns an deach am magnet a dh\u00e8anamh buaidh cuideachd air a neart magnetach. Is e na d\u00f2ighean as cumanta air magnets neodymium a dh\u00e8anamh sintering, bonding, agus leaghadh. Gus d\u00e8anamh cinnteach gu bheil magnet neodymium math agad, tha thu airson magnets a cheannach bho chompanaidh aig a bheil deagh smachd c\u00e0ileachd.<\/strong><\/p>\n

Coltas<\/strong><\/span><\/h2>\n

Is e an ath rud a tha thu airson sgr\u00f9dadh a dh\u00e8anamh air an d\u00f2igh anns a bheil am magnet neodymium a\u2019 coimhead. Tha thu airson sgr\u00f9dadh a dh\u00e8anamh airson sg\u00e0inidhean, sliseagan, agus mar a tha am magnet a\u2019 coimhead. Tha magnets air an sgr\u00f9dadh gu fradharcach airson uireasbhaidhean sam bith ann an cr\u00ecochnachadh uachdar no c\u00f2mhdach. Tha iad air an deuchainn airson adhesion plating. Tha iad air an deuchainn airson seasamh an aghaidh corrach. Bidh iad gan cur ann an spraeadh salainn agus se\u00f2mar taiseachd gus d\u00e8anamh cinnteach gum fuirich an c\u00f2mhdach air a\u2019 magnet.<\/strong><\/p>\n

Tha thu cuideachd airson sgr\u00f9dadh a dh\u00e8anamh air meud a\u2019 magnet. Tha meud agus cumadh a\u2019 magnet cudromach oir tha thu airson gum bi am magnet a\u2019 freagairt far a bheil thu gu bhith ga chuir. Bidh luchd-saothrachaidh a\u2019 tomhas meud a\u2019 magnet a\u2019 cleachdadh calipers, micrometers, no inneal tomhais co-\u00f2rdanachaidh (CMM). Tha thu airson d\u00e8anamh cinnteach gum bi am magnet a\u2019 freagairt gu ceart far a bheil thu gu bhith ga chuir.<\/strong><\/p>\n

<\/strong>Feartan Magnetach<\/strong><\/h2>\n

\"Maoin<\/p>\n

Is e an treas rud a tha thu airson sgr\u00f9dadh a dh\u00e8anamh air neart magnetach a\u2019 magnet. Tha beagan tomhais eadar-dhealaichte ann as urrainn dhut a chleachdadh gus faighinn a-mach d\u00e8 cho l\u00e0idir sa tha am magnet. Is e na tr\u00ec tomhais as cumanta remanence (Br), coercivity (Hc), agus toradh l\u00f9th as \u00e0irde (BHmax).<\/strong><\/p>\n

Is e remanence (Br) an \u00ecre de magnetism a tha air fh\u00e0gail anns a\u2019 magnet \u00e0s deidh dhut a thoirt a-mach \u00e0s an raon magnetach.<\/strong><\/p>\n

Tha Coercivity (Hc) na thomhas air cho cruaidh \u2018s a tha e am magnetism a thoirt a-mach \u00e0s a\u2019 magnet.<\/strong><\/p>\n

Is e toradh l\u00f9th as \u00e0irde (BHmax) na tha de l\u00f9th magnetach as urrainn don magnet a st\u00f2radh. Tha BHmax \u00e0rd cudromach nuair a tha feum agad air magnet l\u00e0idir.<\/strong><\/p>\n

Bidh luchd-saothrachaidh a\u2019 cleachdadh innealan mar magnetometers sampall crathaidh (VSMan) agus permeameters gus na feartan sin a thomhas. Bidh iad a\u2019 toirt magnet, ga chuir anns na h-innealan sin, agus ga ruith tro bhuidheann de dheuchainnean. Bidh na deuchainnean sin a\u2019 cruthachadh l\u00f9ban hysteresis.<\/strong><\/p>\n

Is e deuchainn eile as urrainn dhut a dh\u00e8anamh deuchainn feachd tarraing. Bidh thu a\u2019 cur a\u2019 magnet ann an inneal a thomhaiseas na tha de fheachd a dh\u2019 fheumar gus am magnet a tharraing air falbh bho n\u00ec no am magnet a chumail air n\u00ec. Innsidh an deuchainn seo dhut mar a n\u00ec am magnet san tagradh agad.<\/strong><\/p>\n

Is e aon deuchainn eile as urrainn dhut a dh\u00e8anamh meatair Gauss a chleachdadh. Bidh meatair Gauss a\u2019 tomhas neart raon magnetach a\u2019 magnet. Innsidh an deuchainn seo dhut mu sgaoileadh raon magnetach a\u2019 magnet agus cho l\u00e0idir sa tha am magnet.<\/strong><\/p>\n

 <\/p>\n

C\u00f2mhdach<\/strong><\/span><\/h2>\n

Is e an ath rud a tha thu airson sgr\u00f9dadh a dh\u00e8anamh air a\u2019 ch\u00f2mhdach air a\u2019 magnet. Tha an c\u00f2mhdach air a chuir air magnet gus a dh\u00econ bho chreachadh agus caitheamh. Tha thu airson d\u00e8anamh cinnteach gum fuirich an c\u00f2mhdach air a\u2019 magnet.<\/strong><\/p>\n

Bidh luchd-saothrachaidh a\u2019 d\u00e8anamh deuchainn air a\u2019 ch\u00f2mhdach air a\u2019 magnet gus d\u00e8anamh cinnteach gum fuirich e air a\u2019 magnet. Bidh iad a\u2019 cleachdadh deuchainn teip no deuchainn sgr\u00ecobadh gus faicinn am fuirich an c\u00f2mhdach air a\u2019 magnet.<\/strong><\/p>\n

Bidh iad cuideachd a\u2019 d\u00e8anamh deuchainn gus faicinn an d\u00econ an c\u00f2mhdach am magnet bho mheirge. Bidh iad a\u2019 cur a\u2019 magnet ann an spraeadh salainn agus se\u00f2mar taiseachd gus faicinn an cum an c\u00f2mhdach am magnet bho bhith a\u2019 meirgeadh.<\/strong><\/p>\n

 <\/p>\n

Te\u00f2thachd<\/strong><\/span><\/h2>\n

Is e an ath rud a tha thu airson sgr\u00f9dadh a dh\u00e8anamh air mar a tha am magnet gu bhith ag obair aig te\u00f2thachdan \u00e0rda. Tha magnets Neodymium mothachail air te\u00f2thachdan \u00e0rda. Nuair a nochdas tu magnet gu te\u00f2thachdan \u00e0rda, caillidh e cuid den neart magnetach aige.<\/strong><\/p>\n

Bidh luchd-saothrachaidh a\u2019 d\u00e8anamh deuchainn air mar a bhios magnets a\u2019 coileanadh aig te\u00f2thachdan \u00e0rda. Bidh iad a\u2019 d\u00e8anamh deuchainn ris an canar rothaireachd teirmeach. Bidh iad a\u2019 cur a\u2019 magnet ann an \u00e0mhainn agus ga theasachadh suas gu te\u00f2thachd s\u00f2nraichte.
