Tsis yog tag nrho cov hlau yog hlau nplaum; kub, nyiaj thiab aluminium yog qee qhov piv txwv. Ib qho kev sib txawv loj ntawm kev siv tshuab yog siv los cais cov khoom sib nqus. Thaum sib nqus sib nqus, cov hlau nplaum nyob hauv ob lub nruas sib nqus uas dais kua.

Tsis tas li ntawd, dab tsi sib tov tuaj yeem sib cais los ntawm kev sib nqus sib nqus?

Yog ib feem ntawm lub sib tov muaj Sib nqus koj, ua tau siv a hlau nplaum rau cais tus sib tov . Hlau, npib tsib xee, thiab cobalt yog txhua yam khoom siv Sib nqus . Tsis yog tag nrho cov hlau Sib nqus : kub, nyiaj, thiab txhuas yog cov piv txwv ntawm cov hlau uas tsis yog Sib nqus.

Kuj Paub, cov hlau twg tsis tuaj yeem sib cais los ntawm kev sib nqus sib nqus? Sib nqus sib cais muaj qee qhov kev txwv. Nws cais tsis tau hlau thiab hlau los ntawm nickel thiab Sib nqus stainless hlau.

Ua raws li qhov no, thaum twg koj yuav siv cov sib nqus sib nqus?

Sib nqus sib cais yog ib tug txheej txheem nyob rau hauv uas magnetically susceptible khoom yog muab rho tawm los ntawm ib tug sib tov siv a Sib nqus zog. Qhov no kev sib cais txheej txheem ua tau yuav pab tau nyob rau hauv mining hlau raws li nws yog attracted rau a hlau nplaum.

Leej twg invented magnetic sib cais?

Thawj Sib nqus separator , invented los ntawm John Prince, muaj ob khub ntawm electromagnets nrog ib txoj hlua pub khiav hla lawv.
