Kodi pali kusiyana kotani pakati pa maginito okoka ndi obweza?

Kwa nthawi yaitali maginito akhala akukopa anthu ndi luso lawo lodabwitsa logwiritsa ntchito mphamvu pa zinthu zapafupi popanda kukhudza thupi. Chochitika ichi chimachokera ku mphamvu yaikulu ya maginito yotchedwamphamvu ya maginitoChimodzi mwa zinthu zosangalatsa kwambiri zokhudza mphamvu ya maginito ndi kusiyana pakati pa mphamvu zokopa ndi zothamangitsa zomwe maginito amasonyeza. Kumvetsetsa kusiyana pakati pa zochitika ziwirizi kumaphatikizapo kufufuza dziko la microscopic lamaginitondi khalidwe la tinthu tomwe timayatsidwa.

Malo Okopa Anthu:

Pamene maginito awiri ayandikirana wina ndi mnzake ndi zipilala zawo zosiyana zikuyang'anizana, amasonyeza kukopana. Izi zimachitika chifukwa cha kugwirizana kwa maginito mkati mwa maginito. Maginito ndi madera ang'onoang'ono kumene nthawi zamaginito za atomiki zimayikidwa mbali imodzi. Pokopa maginito, zipilala zosiyana (kumpoto ndi kum'mwera) zimayang'anizana, zomwe zimapangitsa kuti maginito azigwirizana m'njira yomwe imakoka maginito pamodzi. Mphamvu yokopa iyi ndi chiwonetsero cha chizolowezi cha maginito chofuna mphamvu yochepa, pomwe zipilala zamaginito zogwirizana zimathandiza kuti dongosolo lonse likhale lolimba.

Kudzipatula:

Mosiyana ndi zimenezi, chodabwitsa cha kugwedezeka chimachitika pamene mipiringidzo yofanana ya maginito ikuyang'anizana. Pachifukwa ichi, mipiringidzo yolumikizana ya maginito imakonzedwa mwanjira yoti imakana kuyanjana pakati pa maginito awiriwa. Mphamvu yogwedezeka imachokera ku chilengedwe cha mphamvu ya maginito kuti itsutsane pamene mipiringidzo yofananayo ili pafupi. Khalidweli ndi zotsatira za kuyesa kupeza mphamvu yapamwamba pochepetsa kugwedezeka kwa nthawi zamaginito, chifukwa mphamvu yogwedezeka imaletsa mipiringidzo ya maginito kuti isagwirizane.

Mawonekedwe a Microscopic:

Pa mlingo wa microscopic, khalidwe la maginito lingathe kufotokozedwa ndi kuyenda kwa tinthu tating'onoting'ono tomwe timayendetsedwa, makamaka ma elekitironi. Ma elekitironi, omwe ali ndi mphamvu yoipa, amayenda nthawi zonse mkati mwa maatomu. Kuyenda kumeneku kumapanga mphindi yaying'ono ya maginito yogwirizana ndi elekitironi iliyonse. Mu zinthu zomwe zimawonetsa ferromagnetism, monga chitsulo, mphindi zamaginito izi zimayendera mbali imodzi, zomwe zimapangitsa kuti maginito onse a zinthuzo agwire ntchito.

Pamene maginito akukoka, nthawi zamaginito zolumikizana zimalimbitsana, zomwe zimapangitsa kuti maginitowo azigwirizana. Kumbali ina, pamene maginito akubwerera m'mbuyo, nthawi zamaginito zolumikizana zimakonzedwa m'njira yoti zisakhudzidwe ndi mphamvu zakunja, zomwe zimapangitsa kuti pakhale mphamvu yomwe imakankhira maginitowo pakati.
