Cov muaj pes tsawg leeg ntawm cov hlau nplaum kub kub yog hlau, cobalt, npib tsib xee thiab lwm yam atoms nrog cov qauv tshwj xeeb sab hauv, thiab cov atoms lawv tus kheej muaj lub sijhawm sib nqus. Feem ntau, cov txheej txheem ntawm cov ntxhia molecules yog chaotic. Thiab lawv cov cheeb tsam sib nqus cuam tshuam rau ib leeg, tsis tuaj yeem pom cov hlau nplaum, tab sis raws li kev taw qhia ntawm sab nraud quab yuam (xws li magnetic teb), lawv cov kev taw qhia molecular yuav zoo ib yam, qhia cov hlau nplaum, uas feem ntau hu ua hlau nplaum. Cov hlau nplaum tau muab faib ua cov hlau nplaum tas mus li thiab cov hlau mos, cov hlau nplaum ruaj khov ntxiv rau cov hlau nplaum muaj zog, yog li ntawd cov kiv cua ntawm cov khoom sib nqus thiab lub angular momentum ntawm electron tsim ib qho kev taw qhia ruaj khov.
Cov hlau nplaum kub kub tuaj yeem muab faib ua ob pawg: ib qho yog cov hlau nplaum hlau nplaum, suav nrog Nd2Fe14B, samarium cobalt hlau nplaum (SmCo) thiab txhuas nickel cobalt hlau nplaum; Qhov thib ob, cov hlau nplaum ferrite muaj cov qauv tshwj xeeb sab hauv thiab lub sijhawm sib nqus. Hom kub kub hlau nplaum: zoo li tus kub kub hlau nplaum: square high kub hlau nplaum, pobzeb siab kub hlau nplaum, zoo li tus kub kub hlau nplaum, cylindrical kub hlau nplaum, ncig siab kub hlau nplaum, sib nqus bar siab kub hlau nplaum, sib nqus ncej siab kub hlau nplaum, siab kub Cov hlau nplaum: samarium cobalt hlau nplaum, NdFeb siab kub hlau nplaum, ferrite siab kub hlau nplaum, aluminium nickel cobalt kub hlau nplaum, hlau chromium cobalt kub hlau nplaum, ua hauj lwm kub hlau nplaum: Sib nqus Cheebtsam thiab motors kub resistant mus tas li hlau nplaum kub resistant hlau nplaum ntxiv zog magnetism, thiaj li hais tias lub spin ntawm cov khoom sib nqus nrog lub angular momentum ntawm lub electron teem rau hauv ib tug taag kev taw qhia. Cov hlau nplaum mos ntxiv tam sim no (uas kuj yog ib txoj hauv kev ntxiv cov hlau nplaum), cov hlau mos raug tshem tawm los ntawm qhov tam sim no, thiab nws yuav maj mam poob nws cov hlau nplaum.
Cov yam ntxwv muaj pes tsawg leeg ntawm cov hlau nplaum kub kub nrog cov khoom sib txawv yog qhov sib txawv, thiab qhov sib nqus quab yuam loj kuj txawv. Raws li ib txwm muaj, ntau hom hlau nplaum uas muaj qhov kub thiab txias tuaj yeem muab faib ua plaub hom.
