Magnets tuaj hauv ntau qhov sib txawv thiab ntau thiab tsawg. Cov duab no reflect tus kheej lub zog ntawm txhua tus hlau nplaum. Lub zog txiav txim siab ua haujlwm.
Cov hlau nplaum puas tuaj yeem sib txawv?
Magnets tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawgzoo li disc, kheej kheej, horseshoe thiab ib tug xov tooj ntawm lwm yam tshwj xeeb daim ntawv. Feem ntau, cov hlau nplaum loj dua muaj zog dua, tab sis tam sim no ib txwm muaj. Cov hlau nplaum me tuaj yeem txhim kho kom muaj zog los ntawm kev siv cov khoom sib txawv. Cov duab ntawm cov hlau nplaum, txawm li cas los xij, tuaj yeem qhia koj ntau tshaj qhov loj.
Vim li cas peb thiaj muaj ntau hom hlau nplaum?
Peb hom hlau nplaum yog ib ntus, ruaj khov, thiab electromagnets. Cov hlau nplaum raug cais los ntawm lawv qhov chaw ntawm cov hlau nplaum Cov hlau nplaum ib ntus dhau los ua magnetized nyob rau hauv lub xub ntiag ntawm ib tug magnetic teb. … Electromagnets yog tsim los ntawm kev khiav hluav taws xob los ntawm ib lub kauj uas muaj cov tub ntxhais hlau.
Vim li cas cov hlau nplaum zoo li tus nees nees?
Ib tus nees nees zoo li zoo li qhov hnyav dua ntawm lub tog raj kheej ntev. Nws hloov cov kab thauj khoom (lossis Permeance Coefficient) ntawm cov hlau nplaum, kom cov hlau nplaum tsis tuaj yeem demagnetize nws tus kheej. Cov duab nees nees raug xaiv kom cov khoom siv hlau nplaum tuaj yeem nyob tau hlau nplaum Nws yog cov duab coercivity siab, hom.
Cov duab zoo li cas rau cov hlau nplaum?
Cov duab ntawm cov hlau nplaum ua rau nws lub zog. Yog tias cov hlau nplaum muaj qhov taw qhia ntau dua, qhov kawg ntawd yuav muaj zog dua li lwm cov hlau nplaum. Qhov no yog vim tias cov duab cuam tshuam rau kev faib tawm ntawm lub zog sib nqus hauv qhov chaw nws nyob.
