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.

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 .
