yuav hlau nplaum lo rau cam khwb cia hlau

Ua ntej, nws yog ib qho tseem ceeb kom nkag siab tias cov cam khwb cia hlau yog dab tsi thiab nws txawv ntawm lwm hom hlau li cas. Cam khwb cia hlau yog ib hom hlau-carbon alloy uas muaj tsawg kawg yog 2% carbon. Nws muaj qhov qis melting point thiab paub txog nws cov durability thiab kub tuav cov khoom. Nws yog feem ntau siv hauv kev tsim cov lauj kaub ua noj, lauj kaub, thiab lwm yam khoom siv hauv chav ua noj.

Thaum nws los txog rau magnetism, cam khwb cia hlau tsis yog sib nqus. Qhov no txhais tau hais tias yog koj tuav ib lub hlau nplaum mus txog ib daim hlau cam, nws yuav tsis lo rau nws. Txawm li cas los xij, muaj qee qhov kev zam rau txoj cai no. cam khwb cia hlau tuaj yeem ua hlau nplaum yog tias nws los rau hauv kev sib cuag nrog cov hlau nplaum muaj zog txaus, xws li cov hlau nplaum los yog electromagnet.

Yog li, feem ntau, hlau nplaum yuav tsis lo rau cam khwb cia hlau tshwj tsis yog cov cam khwb cia hlau tsis tau hlau nplaum. Qhov no tuaj yeem tshwm sim yog tias cov cam khwb cia hlau raug rau qhov muaj zog txaus sib nqus, xws li cov hlau nplaum uas muaj zog lossis cov hlau nplaum. Thaum lub cam khwb cia hlau tau magnetized, nws yuav khaws qee qib ntawm cov hlau nplaum txawm tias tom qab cov hlau nplaum lossis electromagnet raug tshem tawm.
