Yog tias koj txuas ob kawg ntawm cov xaim mus rau a lub teeb thiab tsim ib lub voj kaw, ces tam sim no ua tau ntws. Hmoov tsis, txawm li cas los xij, tam sim no tsim los ntawm kev txav a hlau nplaum dhau ib kab tsis muab txaus zog sai txaus los ua tiag teeb tus noob . tam sim no ntxiv Lub teeb rov!
Ua raws li qhov xav tau, yuav siv cov hlau nplaum li cas los ua lub teeb?
Tshem cov rwb thaiv tsev los ntawm xoob hlau pieces nrog daim ntawv xuab zeb. Qhwv qhov kawg ntawm cov hlau nyob ib ncig ntawm qhov kawg ntawm cov LED teeb lub teeb . Daim kab xev rau kev ruaj ntseg ntawm lub wired noob mus rau hauv qab ntawm lub canister. Tso lub neodymium hlau nplaum nyob rau hauv lub canister thiab kaw lub hau.
Ib tug kuj yuav nug, lub teeb hlau nplaum yuav kav ntev npaum li cas? Cov lus teb nyob ntawm tus hlau nplaum . Ib ntus hlau nplaum tau poob nws magnetization hauv tsawg dua 1 teev. Neodymium hlau nplaum poob qis dua 1% ntawm lawv lub zog tshaj 10 xyoo. Mus tas li hlau nplaum xws li sintered Nd-Fe-B hlau nplaum nyob magnetized indefinitely.
Ntxiv rau qhov no, cov hlau nplaum puas tuaj yeem siv los tsim hluav taws xob?
Sib nqus teb ua tau ua siv ua hluav taws xob Cov yam ntxwv ntawm hlau nplaum yog siv ua hluav taws xob . Tsiv magnetic teb rub thiab thawb electrons. Tsiv a hlau nplaum nyob ib ncig ntawm ib lub coil ntawm hlau, los yog txav ib co coil ntawm ib ncig ntawm ib hlau nplaum , thawb cov electrons hauv cov hlau thiab tsim ib qho hluav taws xob tam sim no.
Cov hlau nplaum thiab tooj liab xaim hluav taws xob li cas?
A Sib nqus teb rub thiab thawb electrons hauv qee yam khoom ze rau lawv, ua lawv txav mus. Cov hlau zoo li tooj liab muaj cov electrons uas yooj yim txav los ntawm lawv lub orbits. Yog koj tsiv a hlau nplaum sai los ntawm ib tug coil ntawm xov tooj , cov electrons yuav txav - qhov no tsim hluav taws xob.

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
Cov yas puas tuaj yeem nyiam cov hlau nplaum?
Yog li, lub magnetic teb tuaj yeem raug ntxias hauv ib qho ntawm cov hlau. Cov ntaub ntawv uas tsis nyiam cov hlau nplaum zoo li huab cua, ntoo, yas, tooj dag, thiab lwm yam, muaj ib qho permeability ntawm, qhov tseem ceeb, 1. Tsis muaj hlau nplaum induced nyob rau hauv lawv los ntawm anexternal magnetic teb, thiab yog li ntawd, lawv yog notattracted los ntawm ib tug hlau nplaum
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
