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.
