Kev Tsim Kho Lub Nplhaib Magnet

Lub nplhaib hlau nplaum, tseem hu ua lub nplhaib sib nqus, yog ib hom hlau nplaum nrog qhov chaw hollow. Thaum ib qho hluav taws xob tam sim no dhau los ntawm nws, nws tsim ib qho chaw sib nqus perpendicular rau lub nplhaib ntawm qhov chaw. Nws txoj kev tsim kho zoo ib yam li lub nplhaib, muaj ntau lub arc - zoo li daim hlau nplaum nrog qhov chaw hollow. Cov hlau nplaum no feem ntau yog ua los ntawm cov khoom siv hlau nplaum nyuaj, xws li neodymium hlau boron thiab ferrite.
