Nuair a thig e gu beatha fhada de mhagnataichean maireannach, chan eil \u201cd\u00e0ta cr\u00ecochnachaidh\u201d no \u201cbeatha sh\u00ecde\u201d soilleir. Fo ch\u00e0irdean foirfe, faodaidh magnet a chumail a chomas airson raointean magnetach airson bliadhnaichean, eadhon fi\u00f9 \u2018s deicheadan. Ach, faodaidh grunn fhactaran a bhith a\u2019 d\u00e8anamh cron air coileanadh magnet le \u00f9ine, gu s\u00f2nraichte ma nach eil thu a\u2019 l\u00e0imhseachadh no a\u2019 st\u00f2radh e gu ceart.<\/p>\n

Beatha Fada Magnetach<\/strong><\/p>\n

Tha coileanadh magnet maireannach d\u00ecreach co-cheangailte ri a chomas a bhith a\u2019 cumail raon magnetach seasmhach. Is e \u201ccreip magnetach\u201d an adhbhar as motha airson l\u00f9badh ann am feachd magnetach, pr\u00f2iseas n\u00e0darra slaodach far a bheil magnet a\u2019 leigeil le feachdan f\u00e8in-dh\u00econach. Airson magnetan deiseil gu math, tha an atharrachadh seo beag agus faodaidh e gabhail bliadhnaichean gu deicheadan airson nochdadh. Ach, ann an cleachdadh, tha magnetan fo ch\u00f9isean \u00e0rainneachdail agus l\u00e0imhseachaidh a dh\u2019 fhaodadh luathachadh cron air coileanadh.<\/p>\n

Pr\u00ecomh Fhactaran a\u2019 Buntainn ri Coileanadh Magnet<\/strong><\/p>\n

Faodaidh grunn fhactaran buaidh a thoirt air neart agus beatha magnet maireannach, a\u2019 gabhail a-steach call volum, nochdadh do raointean demagnetizing taobh a-muigh, agus teas.<\/p>\n

    \n
  1. Call Volum<\/li>\n<\/ol>\n

    Tha call volum, gu h-\u00e0bhaisteach air sg\u00e0th milleadh corporra no corra, aon de na pr\u00ecomh adhbharan airson l\u00f9badh neart magnetach. Ma tha magnet a\u2019 call stuth, ge bith a bheil e a\u2019 chipping no a\u2019 fulang milleadh corporra eile, tha an raon magnetach a tha e a\u2019 d\u00e8anamh a\u2019 l\u00f9ghdachadh gu co-sh\u00f2nraichte. Gus casg a chur air call volum, d\u00e8an cinnteach gu bheil thu a\u2019 st\u00f2radh magnetan ann an \u00e0rainneachdan glan, tioram. Gu h-\u00e0bhaisteach, bu ch\u00f2ir dhaibh a bhith air an st\u00f2radh anns a\u2019 phacaid bhunaiteach aca gus casg a chur air milleadh r\u00e8 l\u00e0imhseachadh.<\/p>\n

      \n
    1. Raointean Demagnetizing taobh a-muigh<\/li>\n<\/ol>\n

      Tha magnetan mothachail do raointean magnetach taobh a-muigh, gu s\u00f2nraichte bho magnetan nas motha no nas l\u00e0idire st\u00f2radh faisg air l\u00e0imh. Bidh stuthan s\u00f2nraichte, leithid Alnico agus magnetan c\u00e8ramach, nas dualtaiche demagnetization p\u00e0irtach nuair a tha iad fo chasaid nan raointean seo. Faodaidh st\u00f2radh ceart anns a\u2019 phacaid a th\u00e8id sol\u00e1thar leis an neach-reic, le magnetan air an cur ann an loidhnichean airson a ch\u00e8ile a th\u00e0ladh, cuideachadh le casg a chur air seo. Faodaidh roinn eadar diofar she\u00f2rsaichean de magnetan r\u00e8 st\u00f2radh cuideachd cuideachadh le lughdachadh cothroman eadar-theachd.<\/p>\n

        \n
      1. Teas<\/li>\n<\/ol>\n

        Faodaidh te\u00f2thachd \u00e0rd buaidh a thoirt air neart magnet, gu s\u00f2nraichte ma tha e a\u2019 dol thairis air te\u00f2thachd as \u00e0irde a tha aig stuth a\u2019 magnet. Mar eisimpleir, tha cuingealachaidhean te\u00f2thachd as \u00e0irde aig magnetan beathach beartach mu dheidhinn 176\u00b0F, fhad \u2018s a tha magnetan c\u00e8ramach a\u2019 gabhail suas ri 400\u00b0F. Fi\u00f9 \u2018s ma tha magnet gun a bhith fo chasaid te\u00f2thachd extreme, faodaidh te\u00f2thachd meadhanach fad-\u00f9ine luathachadh buaidh corra agus raointean magnetach taobh a-muigh, a\u2019 leantainn gu call coileanadh. St\u00f2radh magnetan ann an \u00e0rainneachdan a\u2019 cumail suas te\u00f2thachd inntinneil daonna.<\/p>\n

        D\u00e8 an \u00f9ine a bu ch\u00f2ir do magnet mairsinn?<\/strong><\/p>\n

        Ma st\u00f2ras tu agus a\u2019 l\u00e0imhseachadh do mhagnatair maireannach gu ceart, cha bhi e a\u2019 call barrachd air 1% de a neart magnetach thar 100 bliadhna. Ach, faodaidh cuid de shuidheachaidhean luathachadh an pr\u00f2iseas seo, a\u2019 d\u00e8anamh cron air neart nas motha le \u00f9ine.<\/p>\n

          \n
        1. Te\u00f2thachd<\/li>\n<\/ol>\n

          Mar a thuirt mi roimhe, bidh te\u00f2thachd os cionn \u00ecre as \u00e0irde a tha air a dhearbhadh airson a\u2019 mhagnatair a\u2019 lughdachadh a neart. D\u00e8an cinnteach gu bheil thu a\u2019 cleachdadh magnetan taobh a-staigh nan cr\u00ecochan te\u00f2thachd aca gus coileanadh fad-\u00f9ine a chumail suas.<\/p>\n

            \n
          1. Buaidh Corporra<\/li>\n<\/ol>\n

            Tha magnetan br\u00e8agha, agus faodaidh buaidh chruaidh milleadh a dh\u00e8anamh orra, a\u2019 laighe buaidh air a neart magnetach. Bi faiceallach nuair a l\u00e0imhseachadh iad gus casg a chur air milleadh corporra no milleadh tubaist.<\/p>\n

              \n
            1. Gluasad<\/li>\n<\/ol>\n

              Tha gluasad faisg air no air magnetan na dh\u00f2igh mh\u00f2r. Bidh teas agus sruthan dealain a th\u00e8id a chruthachadh le pr\u00f2iseas gluasad a\u2019 lughdachadh neart magnetach. Tha an \u00e8ifeachd seo nas motha ma tha an te\u00f2thachd a\u2019 dol thairis air \u00ecre as \u00e0irde a tha aig a\u2019 mhagnatair.<\/p>\n

                \n
              1. Uisgeachadh<\/li>\n<\/ol>\n

                Ma thig uisge a-steach don bhogsa no don chorp de mhagnatair, faodaidh oxidation tachairt, a\u2019 d\u00e8anamh cron air a\u2019 stuth agus a\u2019 lagachadh an coileanadh magnetach. Ma tha am bogsa magnet air a mhilleadh, d\u00e8an e gu sgiobalta gus an neart magnetach a chumail suas agus, ann an cuid de dh\u2019 iarrtasan, airson adhbharan sl\u00e0intealachd.<\/p>\n

                 <\/p>\n

                Cleachd agus Comharrachadh As fhe\u00e0rr<\/strong><\/p>\n

                Gus beatha do mh\u00f2ranan seasmhach a mheudachadh, tha st\u00f2radh ceart agus comharrachadh cudromach. Bidh cumail nan m\u00f2r-ch\u00f2rdte anns an pacaid bh\u00f9th aca agus gan st\u00f2radh ann an \u00e0rainneachd smachdail a\u2019 lughdachadh gu m\u00f2r an cunnart call volum, demagnetization, no call coileanaidh air sg\u00e0th teas. Ma tha magnet agad le eachdraidh st\u00f2raidh amharasach no a tha a\u2019 nochdadh comharran de dh\u2019\u00ecth, faodaidh tu ceumannan a ghabhail gus measadh a dh\u00e8anamh agus dh\u2019fhaodadh tu a ch\u00e0radh a\u2019 chomas aige.<\/p>\n

                Ma tha dragh ort mu shuidheachadh nan m\u00f2r-ch\u00f2rdte nas sine no ma tha thu gun chinnteach mu dheidhinn an d\u00f2igh as fhe\u00e0rr airson an st\u00f2radh, co-chomhairlich rinn. Faodaidh sinn do chuideachadh gus d\u00e8anamh cinnteach gu bheil thu gan l\u00e0imhseachadh gu ceart agus a\u2019 meudachadh beatha do stoc m\u00f2r-ch\u00f2rdte agad.<\/p>\n

                \u00a0<\/strong><\/p>\n

                Co-dh\u00f9nadh<\/strong><\/p>\n

                Le c\u00f9ram ceart, faodaidh m\u00f2r-ch\u00f2rdte seasmhach mairsinn airson deicheadan le call beag air bheag de neart. Tha casg a chur air cunnartan cumanta, leithid te\u00f2thachd \u00e0rd, raointean magnetach taobh a-muigh, buaidh corporra, agus taiseachd, cudromach airson coileanadh nan m\u00f2r-ch\u00f2rdte a chumail suas thar \u00f9ine. Le bhith a\u2019 leantainn nan cleachdaidhean as fhe\u00e0rr seo, faodaidh tu do mh\u00f2r-ch\u00f2rdte a chumail ag obair mar a dh\u2019fheumas tu airson bliadhnaichean ri teachd.<\/p>","protected":false},"excerpt":{"rendered":"
