Taw Qhia Cov Khoom Siv Sib Nqus
Sib nqus cua txias yog lub thev naus laus zis tshiab uas siv cov txiaj ntsig sib nqus ntawm cov khoom sib nqus kom ua tiav tub yees. Lub npe hu ua magnetocaloric effect yog hais txog kev ua kom zoo ntawm lub sij hawm sib nqus ntawm cov ntaub ntawv sib nqus thaum cov ntaub ntawv sib nqus hloov pauv, uas yog, kev hloov pauv ntawm cov hlau nplaum entropy, ua rau cov khoom ua rau nqus, Exothermic tshwm sim.
