tom qab 'N'), qhov muaj zog ntawm cov hlau nplaum. Qib siab tshaj ntawm neodymium hlau nplaum tam sim no yog N52. Ib tsab ntawv
tom qab qib yog hais txog qhov ntsuas kub ntawm cov hlau nplaum. Yog tias tsis muaj cov ntawv tom qab qib, ces cov hlau nplaum
yog tus qauv kub neodymium. Qhov ntsuas kub yog tus qauv (tsis muaj npe) - M - H - SH - UH - EH.
