Peb txhua tus paub qhov ntawd hlau nplaum sib sib zog nqus ncej thiab repel zoo li cov ncej. Tab sis raws nraim hom hlau ua lawv nyiam? Neodymium hlau nplaum paub tias muaj zog tshaj hlau nplaum cov khoom muaj thiab muaj lub zog tuav siab tshaj plaws rau cov hlau no.

Tsis tas li ntawd, dab tsi ntawm cov hlau nplaum repel?

Txhua hlau nplaum muaj ob sab qaum teb thiab sab qab teb ncej. Thaum koj tso tus ncej qaum teb ntawm ib qho hlau nplaum nyob ze ntawm tus ncej qab teb ntawm lwm tus hlau nplaum , lawv yog attracted rau ib leeg. Thaum koj tso zoo li tus ncej ntawm ob hlau nplaum nyob ze ib leeg (sab qaum teb mus rau sab qaum teb los yog sab qab teb mus rau sab qab teb), lawv yuav repel ib leeg.

Tom qab, lo lus nug yog, cov hlau nplaum neodymium puas muaj sab qaum teb thiab sab qab teb? Muaj ob peb txoj hauv kev uas koj tuaj yeem txheeb xyuas qhov (Scientific) North thiab South peb cov neodymium hlau nplaum . Yog koj muaj ib tug compass, qhov kawg ntawm rab koob uas ib txwm taw tes North yuav attracted rau lub Sab Qab Teb tus ncej neodymium hlau nplaum.

Ua raws li qhov xav tau, cov hlau nplaum neodymium yuav kav ntev npaum li cas?

Neodymium hlau nplaum nyob ruaj khov hlau nplaum , thiab poob ib feem ntawm lawv qhov kev ua tau zoo txhua 100 xyoo yog tias khaws cia hauv lawv qhov kev ua haujlwm zoo.

Koj puas tuaj yeem demagnetize neodymium hlau nplaum?

Koj tuaj yeem demagnetize lawv los ntawm cua sov rau Curie kub, tab sis qhov ntawd yuav tsis yooj yim siab, piv txwv li. 350 ° C. Lwm qhov kev xaiv yog kom sov rau qee qhov qis dua thiab siv lub ac me me dua yuav xav tau ntawm chav tsev kub.
