D\u00e8 a th\u2019 ann an Remanence?<\/h1>\n

A bheil thu a\u2019 smaoineachadh carson a bhios magnet a\u2019 fuireach magnetized fad \u00e0s \u00e0s a th\u00e8id \u00e0s a\u2019 raon magnetach? Sin e remanence a\u2019 gabhail \u00e0ite.<\/p>\n

Remanence, no magnetization fh\u00e0gail (Br), is e \u00ecre na magnetachd a ghleus magnet seasmhach a\u2019 cumail \u00e0s d\u00e8idh dha a bhith air a thoirt \u00e0s a\u2019 raon magnetach taobh a-muigh.<\/strong><\/p>\n

Biodh sinn a\u2019 dol nas doimhne a-steach don ch\u00f9is chudromach seo de magnetan seasmhach agus mar a tha e a\u2019 buntainn ri coercivity.<\/p>\n

d\u00e8 a th\u2019 ann an remanence(Br)?<\/h2>\n

Chan eil magnetan d\u00ecreach a\u2019 \u201cd\u00ecochuimhneachadh\u201d an magnetachd. Tha remanence a\u2019 sealltainn cia mheud magnetachd a tha fhathast ann am bathar.<\/p>\n

Tha remanence (Br) air a thomhas ann an Tesla no Gauss agus tha e a\u2019 sealltainn neart na magnetachd a tha air a ghleus nuair nach eil am magnet tuilleadh fo bhuaidh raon magnetach taobh a-muigh.<\/strong><\/p>\n

Saidheans na remanence<\/h3>\n

Tha remanence (Br) a\u2019 nochdadh cho l\u00e0idir sa tha magnet seasmhach a\u2019 cumail ri a chuid feartan magnetach \u00e0s d\u00e8idh magnetachadh. Tha a chruasachd stuth, structar, agus co-thaobhadh raointean a\u2019 dearbhadh a remanence.<\/p>\n

1. Carson a tha Br cudromach<\/strong><\/h4>\n

Tha Br riatanach airson tagraidhean a dh\u2019 fheumas raon magnetach seasmhach gun chumhachd leantainneach. Mar eisimpleir, ann am motaran no gineadairean, tha barrachd remanence a\u2019 ciallachadh coileanadh nas seasmhaiche.<\/p>\n\n\n\n\n\n\n\n

2. Ciamar a th\u00e8id Br a thomhas<\/strong><\/h4>\n

Tha Br air a thomhas le bhith a\u2019 magnetachadh an sampall gu s\u00e0sachd, a\u2019 toirt air falbh an raon taobh a-muigh, agus a\u2019 cl\u00e0radh an magnetization air fh\u00e0gail.<\/p>\n

3. Beachdan mu stuthan<\/strong><\/h4>\n

Stuthan mar Neodimium-\u00ccre-Bor\u00f2n (NdFeB)<\/strong><\/a> <\/span>tha luachan \u00e0rd Br aca, a\u2019 d\u00e8anamh iad freagarrach airson tagraidhean a dh\u2019fheumas magnetachd l\u00e0idir, seasmhach. Tha magnetan SmCo cuideachd \u00e0rd ann an Br ach le barrachd seasmhachd te\u00f2thachd. Air an l\u00e0imh eile, tha magnetan Ferrite nas \u00ecsle ann an Br ach tha iad saor agus resistant do chaitheamh.<\/p>\n

Ann am m\u2019 ghn\u00ecomhachas, chunnaic mi luchd-d\u00e8iligidh a\u2019 tionndadh bho magnetan Ferrite gu NdFeB airson innealan \u00e0rd-ch\u00e0ileachd mar dronean agus EVs oir tha feum aca air Br \u00e0rd airson \u00e8ifeachdas agus dealbhadh teann.<\/p>\n

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

Tha remanence ag innse dhuinn cia mheud de magnetachd seasmhach a tha aig magnet seasmhach \u00e0s d\u00e8idh a bhith ga magnetachadh. Tha e cudromach airson a bhith a\u2019 taghadh am magnet ceart airson gin de na tagraidhean.<\/p>\n
