Cov hlau nplaum puas yog ib qho kev hem thawj rau electronics?

Ntau tus neeg muaj ib hom kev tsis txaus siab txog qhov sib thooj ntawm cov hlau nplaum rau cov khoom siv hluav taws xob, kev txhawj xeeb tias lub vijtsam yuav deformed, cov ntaub ntawv khaws cia yuav ploj mus, thiab lub xov tooj smartphone yuav puas los ntawm cov hlau nplaum. Puas yog tib neeg txoj kev txhawj xeeb tsis muaj tseeb? Los yog cov hlau nplaum puas ua rau muaj kev hem thawj rau cov khoom siv hluav taws xob?
Kev cuam tshuam ntawm cov hlau nplaum ntawm cov khoom siv hluav taws xob
Raws li tsab ntawv ceeb toom ntawm Digital Trends lub vev xaib, Matt Newby (Matt Newby), tus thawj coj ntawm lub vev xaib muag khoom magnet first4magnets, tau piav qhia, "Qhov kev txhawj xeeb no tuaj yeem los ntawm cov khoom siv hluav taws xob yav dhau los, xws li CRT saib thiab TV, uas muaj kev cuam tshuam rau cov hlau nplaum. Thaum cov hlau nplaum muaj zog tau coj los ze rau cov khoom zoo li no, lawv tuaj yeem cuam tshuam cov duab, TV niaj hnub thiab cov saib tsis cuam tshuam los ntawm qhov no. "
Cov khoom siv hluav taws xob niaj hnub no feem ntau - xws li smartphones - tsis cuam tshuam los ntawm cov hlau nplaum me me. Tab sis puas yog qhov tseeb tiag?
Cov nyhuv ntawm cov hlau nplaum ntawm smartphones
Matt hais tias, "Cov hlau nplaum peb ntsib hauv peb lub neej niaj hnub, txawm tias cov hlau nplaum uas muaj zog heev ntawm kev ua lag luam, yuav tsis cuam tshuam rau lub xov tooj smartphone. Qhov tseeb, muaj ntau cov hlau nplaum me me hauv lub xov tooj smartphone, thiab nws yog Ib qho tseem ceeb heev rau lawv ua kom tiav. Piv txwv li, Apple lub Apple Watch tshiab siv lub tshuab hluav taws xob sib nqus induction wireless. "
Txawm li cas los xij, muaj ob peb yam uas tib neeg yuav tsum xav txog ua ntej tso cov hlau nplaum kov lub xov tooj smartphone, Digital Trends tau hais. Matt ceeb toom tias thaj chaw sib nqus, uas tuaj yeem cuam tshuam ib ntus nrog cov compasses thiab magnetometers hauv smartphones, yog qhov hnyav dua li tib neeg xav.
Cov kws tshaj lij ntawm K&J Magnetics, lub chaw muag khoom hlau nplaum, siv lub iPhone los ua cov kev sim ua kom pom qhov cuam tshuam ntawm cov hlau nplaum ntawm cov sensors hauv lub xov tooj smartphone.
Michael Paul, tus kws tshaj lij ntawm K&J Magnetics, tau piav qhia, "Qhov teeb meem peb pom yog tias cov hlau nplaum uas nyob ze tuaj yeem cuam tshuam rau lub ntsuas hluav taws xob sib nqus hauv lub xov tooj thiab lub tshuab ntsuas digital yuav nyeem tsis raug. Yog tias koj ntaus lub xov tooj ntawm tes, cov khoom siv hlau hauv lub xov tooj ntawm tes yuav raug hlau nplaum thiab ua cov hlau nplaum tsis muaj zog, uas yuav ua rau nws nyuaj rau kho lub compass. "
Qee cov neeg siv yuav xav tias qhov no tsis yog vim lawv tsis siv cov ntawv thov compass lawv tus kheej, tab sis qhov ntawd tsis txhais tau tias lwm cov apps tsis cia siab rau lub compass. Piv txwv li, Google Maps siv lub compass los txiav txim qhov taw qhia ntawm lub xov tooj, thiab ntau yam kev ua si siv lub compass los "xav" tus neeg siv cov kev taw qhia.
Apple tau coj qhov tseem ceeb no rau hauv tus account hauv kev tsim cov xov tooj ntawm tes thiab cov khoom siv. Apple hais hauv nws Cov Txheej Txheem Tsim Kev Cai hais tias "Apple pom zoo kom tsis txhob siv cov khoom sib nqus thiab hlau hauv rooj plaub." Cov neeg tsim khoom yuav tsum xyuas kom meej tias cov khoom siv sib nqus sib nqus tsis cuam tshuam los ntawm rooj plaub. Lub iPhone 6 Plus tau txais tshwj xeeb "kev saib xyuas" vim tias cov hlau nplaum tuaj yeem ua rau muaj teeb meem nrog cov duab kho qhov muag thiab lub koob yees duab autofocus.
Cov hlau nplaum tsis tuaj yeem dai koj lub xov tooj, tab sis lawv tuaj yeem cuam tshuam nrog qee qhov haujlwm tseem ceeb, yog li vim li cas thiaj li muaj kev pheej hmoo?
Puas yog hard drives cuam tshuam los ntawm cov hlau nplaum?
Lub tswv yim uas cov hlau nplaum tuaj yeem tshem tawm cov ntaub ntawv los ntawm lub hard drive yog nrov heev, tshwj xeeb tshaj yog hauv cov yeeb yaj kiab thiab TV. Piv txwv li hauv "Breaking Bad," Walter White sim rhuav tshem cov pov thawj ntawm lub hard drive uas siv hluav taws xob loj heev. Puas yog kev ntshai ntawm cov hlau nplaum tshem tawm cov ntaub ntawv los ntawm hard drives dhau lawm?
Matt tau taw qhia tias, "Cov ntaub ntawv sau tseg siv cov khoom sib nqus tuaj yeem raug tshem tawm los ntawm cov hlau nplaum, suav nrog cov ntawv kaw suab, floppy disks, video tapes, thiab credit cards. Yog tias cov ntaub ntawv raug kaw siv cov khoom sib nqus, nws tuaj yeem rhuav tshem los ntawm cov hlau nplaum."
Matt piav qhia tias, "Txoj kev xav, cov hlau nplaum muaj zog txaus los rhuav tshem cov ntaub ntawv ntawm lub hard drive yog tias nws nkag mus rau hauv kev sib cuag ncaj qha rau saum npoo ntawm lub hard drive. Txawm li cas los xij, cov hlau nplaum neodymium yog siv rau hauv lub hard drive los ua haujlwm ntawm kev nyeem / sau caj npab thiab sau cov ntaub ntawv, yog li Lub hard drive yuav tsis cuam tshuam los ntawm cov hlau nplaum ntawm cov lus qhia tshwj xeeb, piv txwv li, lo cov hlau nplaum rau sab nraud ntawm PC rooj plaub yuav tsis muaj kev cuam tshuam rau lub hard drive. "
Cov neeg siv ntawm USB flash drives thiab solid-state drives tsis tas yuav txhawj xeeb. Michael hais tias "USB drives thiab SSDs tsis cuam tshuam los ntawm cov hlau nplaum zoo li qub," Michael hais.
K&J Magnetics engineers sim siv cov hlau nplaum neodymium los rhuav tshem cov ntaub ntawv hauv hard drives, tab sis lawv poob siab. Lawv tso cov hlau nplaum loj rau ntawm ib sab ntawm lub zog tsav mus txog thaum lawv tuaj yeem hnov ​​​​lub suab ntawm cov tshuab ntxhua khaub ncaws, qhia tau hais tias cov hlau nplaum tau ua rau cov tsav sab hauv cov khoom khoov. Txawm li cas los xij, cov ntaub ntawv khaws cia hauv lub hard drive tseem 100 feem pua ​​​​zoo li qub.
Siv cov hlau nplaum loj dua los ua rau ntawm lub hard disk uas tau muab tua, thiab cov ntaub ntawv tsis cuam tshuam tag nrho tom qab lub hard disk qhib. Nws yog qhov tseeb tias feem ntau cov lag luam ua rau lub cev puas tsuaj vim kev cia siab rau cov hlau nplaum kom tshem tawm cov ntaub ntawv tsis ntseeg.
Cov neeg puas yuav tsum txhawj xeeb txog cov hlau nplaum?
"Nyob hauv tsev, peb nyob ib puag ncig los ntawm cov hlau nplaum -- hauv txhua lub computer, hais lus, TV, lub cev muaj zog, smartphone. Peb tsis tuaj yeem nyob tsis muaj hlau nplaum," Matt hais.
Digital Trends tau taw qhia tias cov hlau nplaum zoo li tsis raug, tab sis nws tsim nyog taw qhia tias tib neeg yuav tsum tau ceev faj thaum siv cov hlau nplaum muaj zog. Michael tau piav qhia tias, "Cov hlau nplaum neodymium muaj zog tsis yog cov khoom ua si thiab tsis ntev los no tau tshaj tawm xov xwm ntawm cov khoom ua si nrog cov hlau nplaum tau nqos los ntawm cov menyuam yaus, uas ua rau muaj kev phom sij rau kev noj qab haus huv. yuav tsum tau ua haujlwm tam sim ntawd."
