Lub nplhaib zoo li NdFeB hlau nplaum, tseem hu ua neodymium nplhaib hlau nplaum, yog ib hom hlau nplaum ruaj khov uas muaj lub qhov nyob hauv nruab nrab ntawm lub nplhaib. Cov hlau nplaum no yog tsim los ntawm kev sib xyaw ntawm neodymium, hlau, thiab boron, thiab paub txog lawv cov khoom sib nqus muaj zog thiab ua haujlwm ntev.
Lub nplhaib-zoo li tus tsim ntawm cov hlau nplaum no ua rau lawv zoo rau kev siv ntau yam kev lag luam thiab kev tshawb fawb, nrog rau cov motors, generators, loudspeakers, thiab magnetic bearings. Lawv kuj tuaj yeem siv rau hauv cov khoom siv, xws li cov khoom sib nqus rau cov hnab tes thiab cov hniav nyiaj hniav kub.
Nplhaib zoo li NdFeB hlau nplaum tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab muaj zog, xws li cov hlau nplaum me me uas tuaj yeem haum rau ntawm tus ntiv tes mus rau cov hlau nplaum loj uas muaj ob peb nti hauv txoj kab uas hla. Lub zog ntawm cov hlau nplaum no ntsuas nyob rau hauv cov nqe lus ntawm lawv cov magnetic teb zog, uas feem ntau yog muab nyob rau hauv units ntawm gauss los yog tesla.
