Cov duab ntawm cov hlau nplaum puas cuam tshuam rau nws lub zog?

Qhia:

Magnetsyog cov khoom ntxim nyiam uas ua lub luag haujlwm tseem ceeb hauv txhua yam ntawm peb lub neej niaj hnub, los ntawm cov thev naus laus zis uas peb siv mus rau kev siv hauv kev tshawb fawb thiab kev lag luam. Ib lo lus nug nthuav uas feem ntau tshwm sim yog seb tushlau nplaum ntawm cov duab sib txawvmuaj kev cuam tshuam rau nws lub zog. Hauv tsab xov xwm no, peb yuav ua tib zoo saib cov kev sib raug zoo ntawm cov duab ntawm cov hlau nplaum thiab lub zog ntawm nws cov hlau nplaum.Ntxiv thiab, peb muabmagsafe nplhaibrau koj.

Kev paub yooj yim ntawm cov hlau nplaum:

Ua ntej tshawb nrhiav qhov cuam tshuam ntawm cov duab, nws yog ib qho tsim nyog yuav tsum nkag siab txog cov hauv paus ntsiab lus ntawm cov hlau nplaum. Cov hlau nplaum muaj ob tug ncej - sab qaum teb thiab sab qab teb - zoo li cov ncej tawm tsam ib leeg thiab cov ncej sib txawv nyiam ib leeg. Lub zog ntawm cov hlau nplaum feem ntau yog ntsuas los ntawm nws qhov chaw sib nqus, uas yog thaj chaw nyob ib puag ncig cov hlau nplaum uas nws lub zog tuaj yeem kuaj pom.

Bar Magnet:

Bar hlau nplaum yuav muaj zog dua magnetic teb nyob rau hauv tej cov lus qhia hais txog cov hlau nplaum ntawm lwm cov duab, xws li cylindrical los yog spherical hlau nplaum. Qhov no yog vim hais tias cov duab ntawm ib tug bar hlau nplaum tso cai rau lub magnetic teb mus ncig ntau concentratedly los ntawm qhov kawg.

Disc Magnet:

Cov duab ntawm lubdisc hlau nplaumkuj cuam tshuam rau cov hlau nplaum qhov kev ua tau zoo, suav nrog lub zog hlau nplaum. Cov hlau nplaum disk tuaj yeem pom cov khoom sib txawv hauv cov kev taw qhia sib txawv ntawm cov hlau nplaum ntawm lwm cov duab.

Ring Magnets:

Cov duab ntawm lubnplhaib hlau nplaumkuj cuam tshuam rau kev ua haujlwm ntawm cov hlau nplaum. Ntiv nplhaib hlau nplaum muaj qee yam khoom tshwj xeeb piv rau lwm cov duab ntawm cov hlau nplaum. Nyob rau hauv ib lub nplhaib hlau nplaum, lub magnetic teb yog concentrated nyob ze ntawm qhov chaw ntawm lub nplhaib. Cov duab no tuaj yeem tsim cov hlau nplaum muaj zog, thiab tej zaum yuav muaj qhov sib nqus zoo sib nqus zoo nyob rau hauv thaj tsam nruab nrab ntawm lub nplhaib.

Qhov cuam tshuam ntawm cov duab ntawm Magnetic Strength:

Surface Area and Exposure: Ib yam uas tuaj yeem cuam tshuam rau lub zog hlau nplaum yog nws qhov chaw ntog. Cov hlau nplaum nrog thaj chaw loj dua muaj qhov chaw ntau dua rau cov kab sib nqus kom muaj nyob, uas tuaj yeem ua rau lawv lub zog tag nrho. Qhov no yog vim li cas cov hlau nplaum dav dav tuaj yeem pom cov khoom sib nqus sib txawv dua li nyias, elongated sawv daws yuav.

Uniformity of Shape: Lub uniformity ntawm cov hlau nplaum cov duab kuj plays lub luag hauj lwm. Cov hlau nplaum uas tuav cov duab zoo ib yam yuav muaj qhov sib txawv ntawm cov kab hlau nplaum sib nqus, ua rau muaj zog thiab muaj peev xwm twv tau ntau dua. Cov hlau nplaum tsis zoo li qub tuaj yeem muaj kev cuam tshuam ntawm thaj chaw.

Sib Nqus Domain Alignment: Cov duab ntawm cov hlau nplaum tuaj yeem cuam tshuam qhov kev sib haum xeeb ntawm nws cov khoom sib nqus - thaj chaw microscopic uas atomic hlau nplaum sib dhos lawv cov ncej. Hauv qee cov duab, xws li elongated lossis cylindrical hlau nplaum, ua tiav qhov kev pom zoo ntawm qhov kev sib tw yuav nyuaj dua, uas cuam tshuam rau lub zog sib nqus.

Cov piv txwv tiag tiag hauv ntiaj teb:

Cylindrical Magnetshauv MRI Machine: Hauv kev kho mob, cov hlau nplaum cylindrical feem ntau siv hauv MRI tshuab. Cov duab yog ua tib zoo tsim los muab cov khoom sib nqus thiab muaj zog sib nqus qhov tseem ceeb rau cov duab kom ntxaws.

Flat Magnets nyob rau hauv Speaker Systems: Flat, disc-zoo li tus hlau nplaum feem ntau siv nyob rau hauv hais lus systems. Lub cheeb tsam loj dua tso cai rau qhov chaw sib nqus ntau dua, ua rau tus neeg hais lus ua haujlwm tau zoo.

Xaus:

Thaum cov duab ntawm cov hlau nplaum cuam tshuam nws cov khoom sib nqus, nws tseem ceeb heev uas yuav tsum nco ntsoov tias lwm yam, xws li cov khoom muaj pes tsawg leeg thiab cov txheej txheem tsim khoom, kuj tseem ua lub luag haujlwm tseem ceeb. Cov kws tshaj lij thiab cov kws tshawb fawb ua tib zoo xav txog daim ntawv thov npaj thaum xaiv cov duab hlau nplaum los txhim kho cov hlau nplaum sib nqus thiab ua haujlwm zoo. Kev sib raug zoo ntawm cov duab thiab lub zog ntxiv qhov zoo nkauj rau txoj kev kawm thiab kev siv cov hlau nplaum, thawb cov ciam teb ntawm qhov ua tau nyob rau hauv ntau yam txuj ci thiab kev tshawb fawb.
