Raws li lub cim thib peb ntawm lub ntiaj teb tsis tshua muaj hlau nplaum ruaj khov, Neodymium hlau nplaum yog cov hlau nplaum uas muaj zog tshaj plaws.Neodymium arc magnet, tseem hu ua Neodymium curved magnet, yog ib qho tshwj xeeb ntawm Neodymium hlau nplaum, ces yuav luag tag nrho cov Neodymium arc hlau nplaum yog siv rau ob qho tib si rotor thiab stator hauv cov hlau nplaum ruaj khov (PM) motors, generators, los yog sib nqus couplings.
Neodymium lron Boron (NdFeB) hlau nplaum yog hom tsis tshua muaj ntiaj teb Cov hlau nplaum uas tau txais txiaj ntsig rau nws cov khoom sib nqus zoo kawg nkaus.NdFeB hlau nplaum yog lub npe hu ua lub zog ruaj khov tshaj plaws. hlau nplaum muaj.thiab feem ntau yog siv nyob rau hauv ntau yam daim ntawv thov, los ntawm hluav taws xob motors rau magnetic hniav nyiaj hniav kub.
