Lub lauj kaub hlau nplaum tseem hu ua Round Base Magnets lossis Round Cup Magnets, RB Magnets, khob hlau nplaum, yog lub khob sib nqus sib nqus uas muaj xws li neodymium los yog ferrite nplhaib hlau nplaum encased nyob rau hauv ib lub khob hlau nrog lub countersunk los yog counterbored mounting qhov. Nrog rau hom kev tsim no, qhov sib nqus tuav lub zog ntawm cov sib nqus sib nqus tau muab ntau zaus thiab muaj zog dua li cov hlau nplaum ib leeg.
Lub lauj kaub hlau nplaum yog cov hlau nplaum tshwj xeeb, uas tshwj xeeb tshaj yog cov loj, yog siv hauv kev lag luam raws li cov hlau nplaum muaj. Cov hlau nplaum ntawm lub lauj kaub hlau nplaum yog ua los ntawm neodymium thiab tau muab tso rau hauv lub lauj kaub hlau txhawm rau txhawm rau ua kom cov nplaum nplaum ntawm cov hlau nplaum. Yog vim li cas lawv thiaj li hu ua "pot" hlau nplaum.
