Yog li ntawd, a Sib nqus teb ua tau yuav induced nyob rau hauv ib feem ntawm steel. Cov ntaub ntawv uas tsis yog attracted rau ib tug hlau nplaum zoo li cua, ntoo, yas , tooj dag, thiab lwm yam., muaj ib tug permeability ntawm, qhov tseem ceeb, 1. Tsis muaj hlau nplaum induced nyob rau hauv lawv los ntawm anexternal Sib nqus teb, thiab yog li ntawd, lawv tsis yog nyiam los ntawm a hlau nplaum.

Ib yam li ntawd, tib neeg nug, puas muaj cov hlau nplaum uas nyiam cov yas?

SCIENTISTS Cia siab PLASTIC MAGNET YOG Txaus siab Kev tshawb fawb ntxiv. A hlau nplaum ua los ntawm yas Cov khoom siv tsis siv hlau tau tsim los ntawm cov kws tshawb fawb ntawm Ohio State University thiab Du Pont CentralResearch Laboratory, cov kws tshawb fawb tau hais rau hnub Thursday. Cov kws tshawb fawb tau hais tias qhov kub siab tshaj 170 degrees Fahrenheit.

Tsis tas li ntawd, cov ntaub ntawv dab tsi tuaj yeem thaiv cov hlau nplaum? Thaum kawg, koj yuav xav tau ib co phaj ntawm ntau yam cov ntaub ntawv sim ua daim thaiv. Kuv xav kom: ntoo, Plexiglas, styrofoam, tooj dag, tooj liab, txhuas, hlau, hlau, ntawv, stainless hlau, thiab lwm yam cov ntaub ntawv koj xav tias yuav ua haujlwm.5. Ntsuas lub zog ntawm qhov sib nqus ntawm 2 tso tawm ntawm cov hlau nplaum.

Tsuas yog li ntawd, cov yas puas tuaj yeem ua hlau nplaum?

Lwm cov kws tshawb fawb muaj ua cov hlau nplaum yas , tab sis feem ntau lawv tsuas ua haujlwm ntawm qhov kub tsis tshua muaj siab, lossis lawv cov hlau nplaum ntawm chav tsev kub tsis tshua muaj zog los ua lag luam siv.

Vim li cas cov yas tsis sib nqus?

Bcoz rau ib Sib nqus tshuaj, nws yuav tsum tau ferromagnetic los yog ferrimagnetic tab sis yas tsis yog ntawm lawv thiab cov khoom amorphous tsis tuaj yeem qhia cov cuab yeej ntawm cov hlau nplaum.
