A hlau nplaumyog ib tug hlau nplaum uas attracts hlau.
Muaj ntau hom hlau nplaum, qee qhov yog cov hlau nplaum square, cylindrical hlau nplaum, disc hlau nplaum, thiab lwm yam tshwj xeeb-zoo li cov hlau nplaum.
Cov hlau nplaum tuaj yeem muab faib ua "cov hlau nplaum tas mus li" thiab "cov hlau nplaum tsis ruaj khov". Cov hlau nplaum tas mus li tuaj yeem yog cov khoom ntuj tsim lossis cov khoom tsim los ntawm tib neeg, cov hlau nplaum tsis ruaj khov, tsuas yog nyob rau hauv qee qhov xwm txheej yuav tshwm sim sib nqus.
Cov hlau nplaum tuaj yeem tsim cov hlau nplaum sib nqus thiab muaj cov yam ntxwv ntawm kev nyiam cov tshuaj ferromagnetic. Lawv feem ntau yog siv rau hauv cov neeg hais lus, compasses, koob sib nqus, cov khoom ua si sib nqus, ua lub cev muaj zog, hnab tawv nqaij, lub tswb nrov, lub qhov rooj suctions, induction cookers, generators, thiab lwm yam.
Thaum cov hlau nplaum tau tshwm sim thawj zaug, peb tau siv nws los ua lub compass, uas tau los ua ib qho ntawm plaub qhov kev tsim khoom zoo tshaj plaws ntawm peb lub teb chaws thaum ub thiab tsim lub npe ntawm peb lub teb chaws cov kev vam meej thaum ub thoob ntiaj teb thiab domestically. Qhov thib ob, nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, peb tau pom tias cov hlau nplaum hauv peb lub neej niaj hnub kuj tau pib nce ntxiv. Hauv tshuaj, txoj kev kho mob ntawm nuclear magnetic resonance tau raug tsim. Txoj kev no siv cov khoom ntawm cov hlau nplaum, thiab hauv peb txoj kev siv Thaum lub sijhawm ua haujlwm, koj yuav pom tias cov hlau nplaum muaj txiaj ntsig zoo rau tib neeg lub neej. Lawv tsis tuaj yeem pab peb txheeb xyuas cov kev taw qhia, tab sis kuj tuaj yeem siv rau hauv kev kho mob los pab peb kho qee yam mob thiab qee yam kab mob tshwj xeeb. Cov nyhuv zoo heev. Thaum kawg, peb kuj tau ua lub hauv paus ntsiab lus ntawm hlau nplaum rau hauv lub tsheb ciav hlau maglev, uas tau dhau los ua lub tsheb ciav hlau tshwj xeeb hauv tib neeg lub neej. Nyob rau hauv tus txheej txheem ntawm kev siv nws, peb pom tias hom tsheb ciav hlau no tsis yog tsuas yog taug kev sai dua tab sis kuj tseem nyob hauv cov txheej txheem ntawm kev khiav. Tsis muaj suab hauv.
