Cov hlau nplaum nyiam hlau vim qhov cuam tshuam ntawm lawv cov hlau nplaum ntawm cov hlau. … Thaum raug cov magnetic teb, cov atoms pib kho lawv cov electrons nrog cov khiav ntawm lub magnetic teb, uas ua rau cov hlau magnetized ib yam nkaus.
Cov hlau nplaum twg tsuas yog nyiam hlau?
Ua ntej tshaj, Magnets tsis nyiam hlau xwb. Lawv nyiam tag nrho cov chav kawm ntawm cov ntsiab lus hu ua ferromagnetic cov ntaub ntawv. Cov no suav nrog hlau, npib tsib xee, cob alt, qee cov alloys ntawm cov hlau tsis tshua muaj hauv ntiaj teb, thiab qee cov minerals tshwm sim xws li lodestone.
Puas yog hlau nplaum?
Nyob rau hauv cov khoom xws li hlau, cob alt, thiab npib tsib xee, feem ntau ntawm cov electrons tig mus rau tib txoj kev. … daim hlau tau dhau los ua hlau nplaumQee yam khoom tuaj yeem sib nqus los ntawm hluav taws xob tam sim no. Thaum hluav taws xob khiav los ntawm ib co coil, nws tsim ib magnetic teb.
Puas yog hlau magnetic los yog nonmagnetic?
Iron is a very well-known ferromagnetic metal. Nws yog, qhov tseeb, muaj zog tshaj ferromagnetic hlau. Nws tsim ib qho tseem ceeb ntawm lub ntiaj teb lub hauv paus thiab muab nws cov khoom sib nqus rau peb lub ntiaj teb. Yog vim li cas lub ntiaj teb ua raws li cov hlau nplaum ruaj khov ntawm nws tus kheej.
Vim li cas hlau tsis sib nqus?
Iron yog ferromagnetic (txim rau cov hlau nplaum), tab sis tsuas yog nyob rau hauv ib qho kub thiab lwm yam kev mob. … Hlau yog paramagnetic saum toj no kub thiab tsuas yog tsis muaj zog txaus nyiam rau thaj chaw sib nqus cov khoom sib nqus muaj cov atoms nrog ib nrab-filled electron plhaub.
