Magnets nyiam hlau vim qhov cuam tshuam ntawm lawv qhov chaw sib nqus ntawm cov hlau… teb, uas ua rau cov hlau magnetized zoo li. Qhov no, nyob rau hauv lem, tsim ib tug attraction ntawm ob lub magnetized khoom.
Vim li cas cov hlau nplaum nyiam hlau tab sis tsis yog ntawv?
Nyob rau hauv cov tshuaj feem ntau, sib npaug ntawm cov electrons spin nyob rau hauv opposite lus qhia, uas tshem tawm lawv cov hlau nplaum. Yog vim li cas cov ntaub ntawv xws li ntaub los yog ntawv thiaj li hais tias tsis muaj zog hlau nplaum. Hauv cov khoom xws li hlau, cob alt, thiab npib tsib xee, feem ntau ntawm cov electrons tig mus rau tib qho kev taw qhia.
Vim li cas cov hlau nplaum nyiam qee yam khoom?
Tej zaum koj yuav tau pom tias cov khoom siv hlau nplaum zoo tib yam li cov khoom siv hlau nplaum nyiam. Qhov no yog vim cov hlau nplaum nyiam cov khoom uas tsis muaj cov khoom siv hluav taws xob uas tig mus rau tib qho kev taw qhia Hauv lwm lo lus, qhov zoo uas hloov cov hlau mus rau hauv cov hlau nplaum kuj nyiam cov hlau rau hlau nplaum.
Cov hlau nplaum twg nyiam hlau?
Magnets tuaj yeem nyiam lossis tawm tsam ib leeg. Cov hlau nplaum ruaj khov yog ib yam khoom uas tsim cov hlau nplaum nyob ib ncig ntawm nws tus kheej. Nws yog daim teb no uas ua rau lawv lo rau ib leeg thiab qee hom hlau. Tshwj xeeb, lawv lo rau ferromagnetic cov ntaub ntawvzoo li hlau thiab cov khoom uas muaj hlau, xws li steel.
Vim li cas cov hlau nplaum nyiam hlau tab sis tsis yog Aluminium?
Hlau yog nyiam rau cov hlau nplaum vim nws cov xwm txheej zoo heev. Aluminium, ntawm qhov tod tes, yog qhov sib txawv heev. Txawm hais tias nws tsis deb tom qab ntawm cov conductivity, nws tsis nyiam cov hlau nplaum li hlau.
