Poisson tus piv ntawm electromagnetic ntshiab hlau yog 0.291.
Poisson tus piv yog hais txog qhov sib piv ntawm kev hloov pauv ib txwm mus rau axial ib txwm lim thaum cov khoom raug rau unidirectional nro lossis compression, tseem hu ua transverse deformation coefficient. Nws yog ib qho elastic tas li uas qhia txog kev hloov pauv ntawm cov khoom siv. Rau cov ntaub ntawv isotropic, Poisson tus piv yog qhov tas li, feem ntau txiav txim siab sim.
Electromagnetic ntshiab hlau yog cov hlau zoo uas muaj cov ntsiab lus hlau ntau dua 99.5%, uas muaj cov yam ntxwv ntawm cov pa roj carbon tsawg, tsis muaj leej faj thiab cov phosphorus tsawg. Nws lub cev muaj zog muaj xws li cov cim tshuaj Fe, atomic naj npawb, thiab belongs rau lub caij hloov. Electromagnetic ntshiab hlau yog dav siv nyob rau hauv ntau yam teb xws li kev tsim kho, machinery, tsheb, thiab electronics.
