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.

Cov hlau nplaum puas tuaj yeem ntab cua?
Cov hlau nplaum tsis tuaj yeem ntab hauv huab cua dawb vim yog lub ntiajteb txawj nqus ntawm lub ntiaj teb thiab nws cov magnetic teb tab sis nws tuaj yeem ntab nrog kev pab los ntawm ib qho kev quab yuam sab nraud xws li siv xov, txhua qhov chaw sib nqus sab nraud uas sib npaug ntawm lub ntiaj teb magnetic teb. Cov hlau nplaum me me tig rov qab tig rov qab
Cov hlau nplaum ruaj khov puas poob hlau nplaum?
Yog lawm, nws muaj peev xwm ua tau rau cov hlau nplaum ruaj khov kom poob nws cov hlau nplaum. Muaj peb txoj hauv kev rau qhov no tshwm sim: 2) Ntawm qhov demagnetizing magnetic teb: cov hlau nplaum tas mus li nthuav tawm cov yam ntxwv hu ua coercivity, uas yog lub peev xwm ntawm cov khoom siv los tiv thaiv demagnetized los ntawm kev siv magnetic teb
Koj puas tuaj yeem muab cov hlau nplaum tso rau ntawm lub thawv fuse?
Ib lub hlau nplaum txav mus nyob ze ntawm lub thawv hlau sib txuas yuav ua rau me me surges tam sim no nyob rau hauv lub thawv phab ntsa. Txhua lub hlau nplaum koj yuav muaj nyob ib puag ncig lub tsev tsis tuaj yeem cuam tshuam nrog koj cov khoom siv hluav taws xob hauv tsev
Peb puas tuaj yeem cais tus ncej sib nqus los ntawm cov hlau nplaum?
Hloov chaw, ob lub sib nqus ncej tshwm sim ib txhij los ntawm kev sib sau ua ke ntawm txhua qhov tam sim no thiab lub sijhawm nyob rau hauv cov hlau nplaum. Vim li no, ob tug ncej ntawm ib tug sib nqus dipole yuav tsum yeej ib txwm muaj sib npaug zos thiab opposite lub zog, thiab ob tug ncej tsis tuaj yeem sib cais los ntawm ib leeg
Koj puas tuaj yeem tso cov hlau nplaum rau ntawm lub vaj huam sib luag hluav taws xob?
Feem ntau tsis yog, nws yuav zoo. Txawm li cas los xij, kuv yuav tsum tsis txhob muab cov hlau nplaum muaj zog nyob ze ntawm cov ntsuas hluav taws xob. Qhov tseeb ntawm qee cov qauv tuaj yeem cuam tshuam los ntawm qhov chaw sib nqus, thiab lwm tus muaj cov sensors uas yuav qhia tau tias 'tampering tshwm sim' rau lub tuam txhab hluav taws xob yog tias lawv pom qhov chaw muaj zog
