Kodi Magnet Amapezeka Liti ndi Kuti

Maginito sanapangidwe ndi munthu, koma maginito achilengedwe. Agiriki akale ndi achi China adapeza mwala wachilengedwe wopangidwa ndi maginito

Amatchedwa "maginito". Mwala woterewu umatha kuyamwa chitsulo ting'onoting'ono ndipo nthawi zonse umaloza mbali imodzi ukangogwedezeka mwachisawawa. Oyenda panyanja akale ankagwiritsa ntchito maginito monga kampasi yawo yoyamba kudziwa kumene ali panyanja. Woyamba kupeza ndikugwiritsa ntchito maginito ayenera kukhala achi China, ndiye kuti, kupanga "kampasi" yokhala ndi maginito ndi imodzi mwazinthu zinayi zazikulu zaku China.

M'nthawi ya Warring States, makolo achi China adapeza chidziwitso chochuluka pankhani iyi ya maginito. Poyang'ana zitsulo zachitsulo, nthawi zambiri amakumana ndi magnetite, ndiko kuti, magnetite (makamaka yopangidwa ndi ferric oxide). Zomwe anapezazi zinalembedwa kalekale. Zomwe anapezazi zinalembedwa koyamba ku Guanzi: "pomwe pali maginito paphiri, pali golidi ndi mkuwa pansi pake."

Pambuyo pazaka masauzande akutukuka, maginito akhala chinthu champhamvu m'moyo wathu. Mwa kupanga ma aloyi osiyanasiyana, zotsatira zomwezo zitha kutheka ngati maginito, ndipo mphamvu ya maginito imathanso kusintha. Maginito opanga maginito adawonekera m'zaka za zana la 18, koma njira yopangira maginito amphamvu idachedwa mpaka kupanga maginito.Alnicomu 1920s. Pambuyo pake,Ferrite maginito zinthuidapangidwa ndikupangidwa m'ma 1950s ndipo maginito osowa padziko lapansi (kuphatikiza Neodymium ndi Samarium Cobalt) adapangidwa m'ma 1970. Pakadali pano, ukadaulo wa maginito wapangidwa mwachangu, ndipo zida zamphamvu zamaginito zimapangitsanso kuti zigawozo zikhale zochepa kwambiri.
