Magnets tau ntev txaus siab rau tib neeg nrog lawv lub peev xwm tsis meej los siv zog ntawm cov khoom nyob ze yam tsis muaj kev sib cuag ntawm lub cev. Qhov tshwm sim no yog ntaus nqi rau cov cuab yeej tseem ceeb ntawm cov hlau nplaum hu uahlau nplaum. Ib qho ntawm qhov txaus nyiam tshaj plaws ntawm cov hlau nplaum yog qhov dichotomy ntawm kev nyiam thiab kev tawm tsam cov rog uas pom los ntawm cov hlau nplaum. Nkag siab qhov sib txawv ntawm ob qhov xwm txheej no cuam tshuam nrog kev nkag mus rau hauv lub ntiaj teb microscopic ntawmmagnetic tebthiab kev coj tus cwj pwm ntawm cov khoom raug them.
Kev nyiam:
Thaum ob lub hlau nplaum raug coj los ze rau ib leeg nrog lawv cov ncej sib txawv, lawv nthuav tawm qhov tshwm sim ntawm kev nyiam. Qhov no tshwm sim vim yog qhov sib txawv ntawm cov khoom sib nqus hauv cov hlau nplaum. Magnetic domains yog thaj chaw microscopic uas atomic magnetic moments raug ua raws tib txoj kev. Nyob rau hauv attracting hlau nplaum, cov opposite ncej (sab qaum teb thiab sab qab teb) ntsib ib leeg, ua rau cov magnetic teb interacting nyob rau hauv ib txoj kev uas rub cov hlau nplaum ua ke. Lub zog txaus nyiam no yog qhov tshwm sim ntawm kev nyiam ntawm cov tshuab sib nqus mus nrhiav lub xeev ntawm lub zog qis, qhov twg cov sib nqus sib nqus sib xyaw ua rau muaj kev ruaj ntseg tag nrho ntawm lub cev.
Repulsion:
Hloov pauv, qhov tshwm sim ntawm repulsion tshwm sim thaum zoo li tus ncej ntawm cov hlau nplaum sib ntsib. Nyob rau hauv no scenario, cov sib nqus sib nqus domains yog teem nyob rau hauv xws li ib txoj kev uas lawv tiv thaiv kev cuam tshuam ntawm ob lub hlau nplaum. Lub zog quab yuam tshwm sim los ntawm qhov tshwm sim ntawm cov hlau nplaum sib nqus los tawm tsam ib leeg thaum zoo li cov ncej nyob sib ze. Qhov kev coj cwj pwm no yog qhov tshwm sim los ntawm kev sim ua kom muaj zog dua lub xeev los ntawm kev txo qis kev sib nqus ntawm lub sijhawm sib nqus, vim tias lub zog quab yuam tiv thaiv cov hlau nplaum sib nqus los ntawm kev sib dhos.
Microscopic Kev Pom Zoo:
Ntawm qib microscopic, tus cwj pwm ntawm cov hlau nplaum tuaj yeem piav qhia los ntawm kev txav ntawm cov khoom siv hluav taws xob, tshwj xeeb tshaj yog electrons. Cov hluav taws xob, uas nqa cov nqi tsis zoo, yog nyob rau hauv qhov kev txav mus tas li hauv atoms. Qhov kev txav no tsim lub sijhawm me me sib nqus nrog txhua lub tshuab hluav taws xob. Nyob rau hauv cov ntaub ntawv uas nthuav tawm ferromagnetism, xws li hlau, lub sij hawm sib nqus no zoo sib xws nyob rau hauv tib txoj kev, ua rau tag nrho cov hlau nplaum ntawm cov khoom.
Thaum cov hlau nplaum nyiam, lub sijhawm sib nqus sib nqus sib zog ua ke, tsim kom muaj txiaj ntsig zoo uas rub cov hlau nplaum ua ke. Ntawm qhov tod tes, thaum cov hlau nplaum thim rov qab, lub sijhawm sib nqus sib nqus tau teem rau hauv txoj kev uas tiv thaiv sab nraud, ua rau lub zog uas thawb cov hlau nplaum sib nrug.
Hauv kev xaus, lubqhov sib txawv ntawm cov hlau nplaumattracting thiab repelling lus dag nyob rau hauv kev npaj ntawm magnetic domains thiab tus cwj pwm ntawm charged hais nyob rau hauv lub microscopic theem. Lub zog txaus nyiam thiab tsis txaus ntseeg pom ntawm qib macroscopic yog qhov tshwm sim ntawm cov hauv paus ntsiab lus tswj hwm kev sib nqus. Txoj kev tshawb fawb ntawm cov hlau nplaum tsis yog tsuas yog muab kev nkag siab rau tus cwj pwm ntawm cov hlau nplaum tab sis kuj muaj cov kev siv hauv ntau yam thev naus laus zis, los ntawm hluav taws xob motors mus rau magnetic resonance imaging (MRI) hauv tshuaj. Lub dichotomy ntawm cov hlau nplaum txuas ntxiv ua rau cov kws tshawb fawb thiab cov neeg txhawb nqa zoo ib yam, ua rau peb nkag siab txog lub hauv paus rog tsim lub ntiaj teb nyob ib puag ncig peb. Yog tias koj xav yuav cov hlau nplaum hauv ntau, thov hu rauFullzen!
