D\u00e8 th\u2019 ann am magnetachd maireannach<\/h1>\n

Tha magnetan coltach ri rudan s\u00ecmplidh, ach tha an cumhachd aca ann an feachdan falaichte a tha a\u2019 cruthachadh teicne\u00f2las an latha an-diugh. Bho do f\u00f2n gu motaran dealain, tha magnetachd a\u2019 d\u00e8anamh a h-uile c\u00e0il comasach.<\/p>\n

Tha magnetachd maireannach a\u2019 ciallachadh an raon magnetach cunbhalach a th\u00e8id a chruthachadh le stuthan s\u00f2nraichte gun fheum air st\u00f2r cumhachd taobh a-muigh. Tha e eadar-dhealaichte bho magnetachd brosnaichte, a thachras a-mh\u00e0in nuair a tha raon taobh a-muigh an l\u00e0thair.<\/strong><\/p>\n

Leig dhuinn sgr\u00f9dadh a dh\u00e8anamh air an eadar-dhealachadh eadar magnetachd maireannach agus magnetachd brosnaichte, mar a th\u00e8id magnetan maireannach a dh\u00e8anamh, na feartan aca, agus mar a tha iad a\u2019 cruthachadh gn\u00ecomhachasan air feadh an t-saoghail.<\/p>\n

D\u00e8 th\u2019 ann am magnetachd maireannach agus magnetachd brosnaichte?<\/h2>\n

Tha cuid de magnetan a\u2019 mairsinn gu br\u00e0th, fhad \u2018s a tha feum aig feadhainn eile air cuideachadh airson obrachadh. Tha tuigse air an eadar-dhealachadh a\u2019 nochdadh m\u00f2ran mu mar a tha magnetachd ag obair anns an t-saoghal f\u00ecor.<\/p>\n

Tha magnetachd maireannach air a thogail a-steach agus seasmhach, fhad \u2018s a tha magnetachd brosnaichte sealach agus an urra ri buaidh magnetach taobh a-muigh.<\/strong><\/p>\n

Mar a bhios gach se\u00f2rsa ag obair<\/h4>\n

Tha magnetachd maireannach na thoradh air raointean magnetach air an r\u00e8iteachadh taobh a-staigh stuth. Bidh na raointean sin a\u2019 fuireach ann an \u00e0ite eadhon nuair a th\u00e8id an t-adhbhar taobh a-muigh a thoirt air falbh. Tha an raon f\u00e8in-taice seo a\u2019 ciallachadh nach fheum am stuth st\u00f2r cumhachd.<\/p>\n

Tha magnetachd brosnaichte, air an l\u00e0imh eile, a\u2019 tachairt nuair a bhios n\u00ec nach eil mar as trice magnetach a\u2019 f\u00e0s magnetach le bhith faisg air raon magnetach. Bidh an n\u00ec a\u2019 fuireach magnetach d\u00ecreach fhad \u2018s a tha e fosgailte. Tha am prionnsapal seo air a chleachdadh ann an iomadh tagradh dealain leithid innleadairean agus electromagnetan.<\/p>\n

Magnetan maireannach<\/span><\/a> tha cudromach ann an dealbhadh teicne\u00f2lais. Mar eisimpleir, nuair a bha mi ag obair air c\u00f2dan motair<\/span><\/a> airson carbadan dealain beaga, sh\u00e0bhail taghadh an stuth magnet maireannach ceart \u00e0ite agus cosgais mh\u00f2r. Aig an aon \u00e0m, chleachd sinn magnetachd brosnaichte ann an tagraidhean mothachairean far an robh feum air an raon atharrachadh a r\u00e8ir an t-slighe a-steach.<\/p>\n

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

Bidh magnetachd maireannach seasmhach thar \u00f9ine gun bhuaidh taobh a-muigh, ga dh\u00e8anamh riatanach ann an dealan, motaran, agus innealan l\u00e0itheil.<\/p>\n
