Kodi Kusiyanitsa Pakati pa Maginito Okopa ndi Kubweza Ndi Chiyani?

Maginito akhala akusangalatsa anthu kwa nthawi yayitali ndi kuthekera kwawo kodabwitsa kogwiritsa ntchito zinthu zapafupi popanda kukhudza. Izi zimachitika chifukwa cha zinthu zofunika kwambiri za maginito zomwe zimadziwika kutimagnetism. Chimodzi mwa zinthu zochititsa chidwi kwambiri za maginito ndi kusiyana pakati pa kukopa ndi kuthamangitsa mphamvu zomwe zimawonetsedwa ndi maginito. Kumvetsetsa kusiyana pakati pa zochitika ziwirizi kumaphatikizapo kufufuza mu dziko la microscopicmaginito mindandi khalidwe la particles choyimbidwa.

Zokopa:

Pamene maginito awiri abweretsedwa pafupi wina ndi mzake ndi mitengo yawo yoyang'anizana, amawonetsa chodabwitsa chokopa. Izi zimachitika chifukwa cha kulumikizana kwa madera a maginito mkati mwa maginito. Maginito a maginito ndi madera ang'onoang'ono pomwe ma atomiki maginito amayendera mbali imodzi. Pokopa maginito, mitengo yosiyana (kumpoto ndi kumwera) imayang'anizana, zomwe zimapangitsa kuti mphamvu za maginito zigwirizane m'njira yomwe imakoka maginito pamodzi. Mphamvu yochititsa chidwiyi ndi chiwonetsero cha chizolowezi cha maginito kufunafuna mphamvu yotsika, pomwe maginito ogwirizana amathandizira kuti dongosolo lonse likhale lokhazikika.

Kubweza:

Mosiyana ndi zimenezi, chodabwitsa cha kukana chimachitika pamene ngati mitengo ya maginito kuyang'anizana. Muzochitika izi, maginito omwe ali ndi maginito amakonzedwa m'njira yoti asagwirizane ndi maginito awiriwa. Mphamvu yonyansa imachokera ku chikhalidwe cha maginito kutsutsana wina ndi mzake pamene ngati mitengo ili pafupi. Khalidweli ndi chotsatira cha kuyesa kupeza mphamvu yapamwamba pochepetsa kuyanjanitsa kwa nthawi ya maginito, chifukwa mphamvu yonyansa imalepheretsa madera a maginito kuti agwirizane.

Mawonekedwe a Microscopic:

Pamlingo wa microscopic, machitidwe a maginito amatha kufotokozedwa ndikuyenda kwa tinthu tating'onoting'ono, makamaka ma elekitironi. Ma electron, omwe ali ndi mphamvu yolakwika, amayenda mosalekeza mkati mwa maatomu. Kuyenda uku kumapanga kamphindi kakang'ono ka maginito kogwirizana ndi electron iliyonse. Muzinthu zomwe zimawonetsa ferromagnetism, monga chitsulo, nthawi zamaginito izi zimakonda kulunjika mbali imodzi, zomwe zimapangitsa kuti zinthuzo zikhale ndi mphamvu yamagetsi.

Maginito akamakopeka, nthawi yolumikizana ndi maginito imalimbitsana, kupangitsa kuti maginito agwirizane. Kumbali ina, maginito akamathamangitsa, maginito omwe amalumikizana amakonzedwa m'njira yotsutsana ndi mphamvu yakunja, zomwe zimatsogolera ku mphamvu yomwe imakankhira maginito.
