Helmholtz Coils ua haujlwm li cas

Lub Helmholtz coil feem ntau muaj ob lub voj voog sib luag ntawm tib lub vojvoog thiab tus lej ntawm cov lem, uas yog tsau rau ntawm ib qho axis thiab nws lub vojvoog yog sib npaug ntawm qhov deb ntawm lawv. Qhov kev ncua deb ntawm lawv feem ntau hu ua "dav" ntawm Helmholtz kauj.

Thaum ob lub coils dhau tam sim no nyob rau tib txoj kev, lawv tsim ib qho chaw sib nqus. Qhov chaw sib nqus no tuaj yeem piav qhia los ntawm Maxwell qhov sib npaug. Txij li thaum Helmholtz coil yog symmetrical, lub magnetic teb nws tsim yog sib xws raws nws axis.

Thaum ob lub coils tau muab nrog rov qab tam sim no, lub superposition tsis muaj zog ntawm cov hlau nplaum, yog li ntawd ib cheeb tsam uas cov hlau nplaum yog xoom tshwm.

Cov ntaub ntawv tseem ceeb siv hauv kev tsim cov Helmholtz Coils

Kev xaiv cov khoom siv rau kev tsim Helmholtz coils yog qhov tseem ceeb rau kev ua tiav qhov kev xav tau thiab ua haujlwm ntev. Qee cov ntaub ntawv tseem ceeb siv hauv kev tsim Helmholtz coils suav nrog:

Tooj liab:Tooj liab yog ib qho kev xaiv rau cov kauj vab windings vim nws cov hluav taws xob hluav taws xob siab thiab thermal stability.

Cov ntaub ntawv tsis sib nqus:Txhawm rau txo qis kev cuam tshuam nrog cov hlau nplaum, cov khoom tsis sib nqus xws li txhuas lossis stainless hlau feem ntau yog siv rau cov coil qub thiab cov qauv txhawb nqa.

Cov ntaub ntawv insulating:Rwb thaiv tsev yog tsim nyog los tiv thaiv luv luv Circuit Court thiab txo lub zog poob. Cov ntaub ntawv zoo li enamel lossis polyimide daim kab xev feem ntau yog siv los thaiv cov coil windings.

Ferromagnetic cores:Qee zaum, ferromagnetic cores ua los ntawm cov ntaub ntawv xws li hlau lossis ferrite tuaj yeem siv los txhim kho lub zog sib nqus thiab ua kom pom tseeb.

Ntoo tej zaum yuav yog ib qho kev xaiv tsis zoo tab sis siv tau rau kev tsim Helmholtz coils. Thaum tsis siv ntau hauv kev tsim coil, ntoo tuaj yeem muab cov txiaj ntsig tshwj xeeb xws li nws cov khoom insulating thiab muaj peev xwm ua kom muaj kev vibrations. Tsis tas li ntawd, ntoo tuaj yeem ua tau yooj yim zoo li tus thiab kho kom tau raws li cov qauv tsim tshwj xeeb, ua rau nws muaj ntau yam khoom xaiv rau coil qub thiab txhawb cov qauv.

Kev xaiv cov ntaub ntawv tsim nyog yog nyob ntawm cov yam ntxwv xws li lub zog hlau nplaum uas xav tau, kev ua haujlwm, thiab kev txiav txim siab nqi.

Kev Ntsuas Cov Yam Ntxim Saib Ntxim Ua Nyob Mus Ib Txhis Nrog Helmholtz Chev

Sib nqus teb yog qhov tsis pom, yog li tsis muaj txoj hauv kev los qhia tias cov hlau nplaum zoo lossis qhov phem tsuas yog saib nws. Muaj ntau yam cuab yeej rau kev sim muaj, tab sis ib qho yooj yim thiab nrov tshaj plaws yog Helmholtz coil. Txuas nrog lub fluxmeter, koj tuaj yeem siv nws los ntsuas lub sijhawm sib nqus lossis lub sijhawm dipole ntawm cov hlau nplaum ruaj khov.

Nws ua haujlwm li cas
Lub Helmholtz coil ntes cov kab sib nqus los ntawm cov hlau nplaum, zoo ib yam li siv tus npauj npaim net.
Tsuas yog hais txog ib qho hlau qhwv li ib lub kauj tuaj yeem siv los ntes thiab ntsuas cov teb uas tsim los ntawm cov hlau nplaum, tab sis kom ua kom muaj kev nkag siab zoo thiab siv tau, kev npaj tshwj xeeb ntawm ob qhov ua haujlwm zoo tshaj plaws:

Qhov kev npaj no yog thawj zaug piav txog lej los ntawm German physicist Hermann von Helmholtz, thiab cov txheej txheem coil tau raug hu ua nws lub meej mom. Lub Helmholtz coil muaj ob qhov sib nqus sib nqus sib nqus uas tau muab tso rau hauv ib qho axis. Muaj ib lub kauj ntawm txhua sab ntawm qhov chaw sim uas txhua tus qauv hlau nplaum muab tso rau. Tus nqi ntawm cov kab hlau nplaum tsim thiab ntes los ntawm Helmholtz coil yog ncaj qha proportional rau lub zog ntawm cov qauv hlau nplaum. Txij li thaum lub ntim thiab cov khoom yog cov khoom ruaj khov, kev ntes cov kab hlau nplaum qhia ib qho yog tias cov hlau nplaum raug hlau nplaum zoo.

Yuav siv li cas
Rau kev ntsuas Helmholtz coil, lub kauj yuav tsum tsawg kawg yog peb zaug loj dua li cov hlau nplaum. Lub kauj yog txuas nrog lub fluxmeter. Cov hlau nplaum yog muab tso rau hauv nruab nrab ntawm lub kauj, lub fluxmeter yog xoom tawm, thiab cov hlau nplaum yog rub ncaj nraim ntawm lub kauj. Lub fluxmeter qhia seb muaj pes tsawg ntawm cov kab hlau nplaum raug ntes los ntawm lub kauj. Feem ntau, qhov tsawg kawg nkaus tus nqi raug xam ua ntej.

Kev sib haum xeeb thiab ceev
Ib qho ntawm ntau qhov zoo ntawm Helmholtz coil ntsuas yog nws qhov kev zam rau qhov sib txawv. Tus neeg siv A yuav tau txais kev nyeem zoo tib yam li Tus Neeg Siv B lossis Tus Neeg Siv C. Thaum teeb tsa tiav, qhov ntsuas tsuas siv ob peb vib nas this, qiv nws tus kheej los siv ntau qhov chaw tsim khoom.

Qhov sib txawv ntawm Magnetic Flux thiab Sib Nqus Chev

Sib nqus flux, tseem hu ua magnetic flux, yog tag nrho cov xov tooj ntawm cov kab hlau nplaum hla dhau ib qho chaw hla ntu, sawv cev los ntawm Φ, thiab chav tsev yog Web (Bot) Wb.
Kev qhia ntawm cov hlau nplaum sib nqus hla dhau ntawm lub kauj yog: Φ=B * S (qhov twg B yog qhov sib nqus induction thiab S yog thaj tsam ntawm lub kauj.)

Qhov sib nqus flux ntawm cov hlau nplaum permeable yog loj dua li ntawm huab cua (nqus); Piv txwv li, lub transformer yog ib qho cuab yeej uas ua ke lub zog los ntawm kev hloov cov hlau nplaum sib nqus. Yog hais tias qhov thib ob ntawm lub transformer yog luv luv, lub magnetic flux yuav raug thaiv thiab input impedance yuav me me.

Sib nqus induction siv - tus naj npawb ntawm magnetic teb kab dhau los ntawm ib chav tsev cheeb tsam perpendicular mus rau cov kev taw qhia ntawm lub magnetic teb kab, kuj hu ua qhov ntom ntawm magnetic teb kab, kuj hu ua magnetic flux ntom, sawv cev los ntawm B, thiab chav tsev yog tex ( Slav) T.
Cov hlau nplaum sib nqus tau hais nyob rau hauv kev ua lag luam yog hais txog lub cylindrical ferrite core nrog rau hauv lub qhov, los ntawm cov hlau tuaj yeem hla los ntawm kev cuam tshuam electromagnetic cuam tshuam (EMI suppression).

Lub magnetosphere yog lub ntiaj teb nyob deb magnetic teb. Nws yog cov khoom ntawm kev sib cuam tshuam ntawm lub ntiaj teb magnetic teb thiab hnub ci cua. Cov ciam teb sab nraud ntawm lub magnetosphere yog magnetopause, uas tuaj yeem ncav cuag qhov chaw ntawm 13,000 mais. Nws yog lub nplhaib sab nraud tshaj plaws nyob ib ncig ntawm lub ntiaj teb thiab nyob deb tshaj qhov kev txwv sab nraud ntawm lub ntiaj teb huab cua. Yog li ntawd, lub magnetosphere yog hu ua lub super sab nrauv. Lub txheej txheej ntawm lub ntiaj teb. Magnetic Circle Vim qhov kev ua ntawm lub hnub ci cua, lub voj voog zoo tagnrho toroidal tsis muaj lawm. Lub siab ntawm lub hnub ci cua compresses lub magnetosphere nyob rau sab uas tig rau lub hnub, qhov twg cov magnetic teb kab yuav luag squeezed ua ke thiab lub magnetosphere yuav nqaim; Thaum nyob rau sab nraud ntawm sab nraud ntawm lub hnub, sab saum toj ntawm lub magnetosphere txuas mus deb thiab cov kab hlau nplaum sib nqus tau sib sib zog nqus heev. , lub magnetosphere yuav dav. Yog li ntawd, cov duab ntawm lub magnetic coil yog me ntsis zoo ib yam li cov tsos ntawm ib tug comet.

Lub siab ntawm lub hnub ci cua compresses lub magnetosphere nyob rau sab uas tig rau lub hnub, qhov twg cov magnetic teb kab yuav luag squeezed ua ke thiab lub magnetosphere yuav nqaim; Thaum nyob rau sab nraud ntawm sab nraud ntawm lub hnub, sab saum toj ntawm lub magnetosphere txuas mus deb thiab cov kab hlau nplaum sib nqus tau sib sib zog nqus heev. , lub magnetosphere yuav dav. Yog li ntawd, cov duab ntawm lub magnetic coil yog me ntsis zoo ib yam li cov tsos ntawm ib tug comet. Lub magnetosphere plays lub luag haujlwm loj hauv kev tiv thaiv lub neej ntawm qhov chaw. Nws ntes cov khoom uas tsim kev puas tsuaj rau tib neeg thiab lub neej coj los ntawm lub hnub ci cua thiab kaw lawv hauv magnetosphere kom lawv tsis tuaj yeem ncav cuag hauv av thiab tsuas yog khiav tawm ntawm magnetotail. tib neeg thiab nyob los ntawm kev puas tsuaj.

Thaum muaj kev thab plaub ntawm qhov tsawg zaus kawg, nws raug nquahu kom lub cable raug mob nyob ib ncig ntawm 2 mus rau 3 lem. Thaum muaj kev thab plaub ntawm qhov kawg siab, nws tsis tuaj yeem raug mob ib puag ncig thiab yuav tsum siv lub nplhaib sib nqus ntev dua.
