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.
Pom zoo:
Puas yog cov hlau nplaum ua los ntawm cov hlau nplaum?
Natural magnets muaj nyob rau hauv lub ntiaj teb thiab yog nplua nuj nyob rau hauv ib tug hlau ntxhia hu ua magnetite. Cov hlau nplaum uas tsim los ntawm tib neeg tau tsim nyob rau hauv ib lub chaw sim los ntawm kev noj cov hlau alloys thiab ua lawv kom haum rau tus nqi .
Puas yog cov hlau nplaum muaj zog dua li cov hlau nplaum ruaj khov?
Electromagnets muaj txiaj ntsig tseem ceeb ntawm kev tswj hwm lawv lub zog sib nqus - ob qho tib si los ntawm kev tig cov hlau nplaum rau lossis tawm thiab los ntawm kev kho qhov tam sim no. Lawv kuj tseem muaj rub lub zog ntau dua li cov hlau nplaum ruaj khov Qee qhov kev kwv yees tso cov hlau nplaum loj tshaj plaws ntawm 20 npaug zog dua li cov hlau nplaum ruaj khov .
Koj puas tuaj yeem khov cov nplaum nplaum nplaum nplaum nplaum?
Yog, koj tuaj yeem khov cov nplaum nplaum nplaum nplaum rau ib ncig ntawm 3 lub hlis. Koj tuaj yeem khov cov nplaum nplaum nplaum nplaum nplaum uas tsis tau ci los yog ci uas txhais tau tias koj tuaj yeem khov cov khoom seem ntawm cov paj npleg.
Vim li cas thiaj siv cov nplaum nplaum nplaum?
Raws li American Academy of Dermatology, exfoliation tuaj yeem ua rau koj cov tawv nqaij zoo dua qub thiab txhim kho cov txiaj ntsig ntawm cov tshuaj pleev ib ce los ntawm kev txhim kho kev nqus. Kev exfoliation tsis tu ncua kuj tseem tuaj yeem pab tiv thaiv cov pores txhaws, ua rau tsawg dua tawg .
Vim li cas ib yam khoom hlau tsis muaj hlau nplaum nyiam rau cov hlau nplaum?
Thaum cov hlau nplaum raug coj los ze rau cov khoom siv ferromagnetic yav dhau los uas tsis muaj hlau nplaum, nws ua rau cov hlau nplaum hauv zos ntawm cov khoom uas tsis zoo li cov ncej ze tshaj, ib yam li hauv. unmagnetized khoom rau cov hlau nplaum raws li daim duab hauv .
