Uyini Umehluko Phakathi Kwezibuthe Ezikhangayo Nokuxosha?

Omazibuthe kudala bethakazelisa isintu ngekhono labo elingaqondakali lokusebenzisa amandla ezintweni eziseduze ngaphandle kokuthintana ngokomzimba. Lesi simo sibangelwa impahla eyisisekelo kazibuthe eyaziwa ngokuthiuzibuthe. Esinye sezici ezithakazelisa kakhulu zikazibuthe yi-dichotomy phakathi kwamandla okuheha nokuxosha aboniswa ngozibuthe. Ukuqonda umehluko phakathi kwalezi zimo ezimbili kuhilela ukuhlola umhlaba omncane we-microscopicizinkundla kazibuthekanye nokuziphatha kwezinhlayiya ezishajiwe.

Okuhehayo:

Lapho omagnethi ababili besondezwa komunye nomunye izigxobo zabo eziphambene zibhekene, babonisa into ekhangayo. Lokhu kwenzeka ngenxa yokuqondaniswa kwezizinda kazibuthe ngaphakathi komazibuthe. Izizinda zikazibuthe ziyizifunda ezincane lapho izikhathi zikazibuthe ze-athomu ziqondaniswe ohlangothini olufanayo. Ekuheheni ozibuthe, izigxobo eziphambene (enyakatho naseningizimu) ziyabhekana, okuholela ekutheni amandla kazibuthe ahlangane ngendlela edonsa omazibuthe. La mandla akhangayo awukubonakaliswa kokuthambekela kwezinhlelo kazibuthe zokufuna isimo samandla aphansi, lapho izizinda kazibuthe eziqondanisiwe zifaka isandla ekuzinzeni okuphelele kwesistimu.

Ukwenqaba:

Ngokuphambene, isenzakalo sokuhoxisa senzeka lapho izigxobo zikamazibuthe zibhekene. Kulesi simo, izizinda kazibuthe eziqondanisiwe zihlelwe ngendlela yokuthi zimelana nokuxhumana phakathi kwamagnethi amabili. Amandla anyanyekayo avela kumvelo engokwemvelo yezinkambu kazibuthe ukuze aphikisane lapho njengezigxobo ziseduze. Lokhu kuziphatha kuwumphumela womzamo wokuthola isimo samandla aphezulu ngokunciphisa ukuqondanisa kwezikhathi zikazibuthe, njengoba amandla anyanyekayo avimbela izizinda kazibuthe ukuthi zihambelane.

I-Microscopic Perspective:

Ezingeni le-microscopic, ukuziphatha kozibuthe kungachazwa ukunyakaza kwezinhlayiya ezishajiwe, ikakhulukazi ama-electron. Ama-electron, aphethe ukushajwa okunegethivu, anyakaza njalo ngaphakathi kwama-athomu. Lokhu kunyakaza kudala umzuzu omncane kazibuthe ohlotshaniswa ne-electron ngayinye. Ezintweni ezibonisa i-ferromagnetism, njenge-iron, lezi zikhathi kazibuthe zivamise ukuqondanisa ohlangothini olufanayo, okuholela kumagnetization iyonke lento.

Lapho omazibuthe beheha, izikhathi zikazibuthe eziqondanisiwe ziyaqinisana, zidale umthelela ohlanganisayo ohlanganisa omazibuthe. Ngakolunye uhlangothi, lapho ozibuthe bexosha, izikhathi zikazibuthe eziqondile zihlelwa ngendlela ephikisana nethonya langaphandle, okuholela emandleni aphusha omazibuthe bahlukane.
