Dab tsi yog qhov sib txawv ntawm cov hlau nplaum thiab cov hlau nplaum?

Qhov sib txawv ntawm cov hlau nplaum thiab cov hlau nplaum yog qhov ntawd
1. Lub tswv yim. Cov hlau nplaum yog cov hlau hloov los ntawm cov txheej txheem magnetization hauv kev lag luam niaj hnub, uas yog, cov hlau uas tau txais cov hlau nplaum los ntawm kev siv tshuab. Magnet yog ib lub pob zeb sib nqus, uas yog, lub ntuj ore. Nws tuaj yeem paub los ntawm lub tswv yim tias cov hlau nplaum yog "hlau" thiab cov hlau nplaum yog "pob zeb".
2. Cov khoom xyaw. Cov hlau nplaum feem ntau yog ua los ntawm hlau (Fe), nickel (Ni), cobalt (Co) atoms thiab lawv cov alloys. Thiab magnetite, nws muaj pes tsawg leeg yog ferric oxide (Fe3O4). Hais txog kev muaj pes tsawg leeg, ob qho tib si kuj txawv.
3. Cov duab. Cov hlau nplaum yog tsim los rau hauv cov ntaub ntawv hlau los ntawm cov txheej txheem txheej txheem tom qab, yog li lawv tuaj yeem muaj ntau yam duab, xws li cov hlau nplaum square, cov hlau nplaum zoo li cov hlau nplaum, cov hlau nplaum tshwj xeeb, cov hlau nplaum cylindrical, cov hlau nplaum hlau nplaum thiab cov hlau nplaum square bar, thiab lwm yam. Cov neeg yuav Raws li koj qhov kev xav tau tiag tiag, tau txais cov duab ntawm cov hlau nplaum uas tuaj yeem ua tau raws li cov txheej txheem.
Lub magnetite yog ib yam ntawm ntuj ore, yog li nws yuav ib txwm muaj ib tug ntxiag tsos. Lub ntsej muag tag nrho yog qhov tsis sib xws, los yog roughly square, los yog roughly round, los yog roughly triangular, nrog ntau npoo thiab ces kaum, thiab tus ntoo khaub lig seem tsis zoo huv si.
4. Sib nqus loj. Rau cov hlau nplaum, rau qee qhov, raws li cov txheej txheem cov khoom yuav tsum tau, cov hlau nplaum tuaj yeem hloov pauv los ntawm qhov me mus rau qhov loj, thiab tib neeg tuaj yeem tsim cov khoom siv hlau nplaum. Thaum cov hlau nplaum ntawm cov hlau nplaum ruaj khov, cov hlau nplaum ntawm lawv cov tsiaj feem ntau tsis muaj zog.
5. Sib nqus ruaj khov. Cov hlau nplaum tsis tuaj yeem raug hlau nplaum tas mus li, tshwj xeeb tshaj yog cov hlau nplaum, uas tuaj yeem sib nqus thaum muaj zog. Tab sis cov hlau nplaum yeej ib txwm yog hlau nplaum.
6. Daim ntawv thov. Magnets muaj ntau yam kev siv. Hauv cov khoom siv hauv tsev thiab txawm tias satellite missiles, thiab lwm yam, koj tuaj yeem pom cov hlau nplaum ntawm ntau cov duab koom nrog nws. Cov hlau nplaum feem ntau yog siv nyob rau hauv lub neej niaj hnub raws li kev pabcuam kev noj qab haus huv hauv cov tshuaj suav tshuaj. Los ntawm kev xav ntawm Suav tshuaj, cov hlau nplaum muaj cov nyhuv ntawm kev sib haum xeeb ntawm tib neeg lub cev.
