Tso lub neodymium hlau nplaum nyob rau hauv lub canister thiab kaw lub hau. Tuav lub kaus mom ntawm koj tus ntiv tes xoo thiab lub forefinger kom lub hau tsis txhob xoob, co lub kaus poom rov qab mus rau teeb tus noob.

Ib yam li ib tug yuav nug, nws puas tuaj yeem teeb lub teeb nrog cov hlau nplaum?

Yog tias koj txuas ob kawg ntawm cov xaim mus rau a lub teeb thiab tsim ib lub voj kaw, ces tam sim no tuaj yeem ntws. Hmoov tsis, txawm li cas los xij, tam sim no tsim los ntawm kev txav a hlau nplaum dhau ib lub xaim tsis muaj zog txaus sai txaus los ua tiag tiag teeb tus noob.

Ib yam li ntawd, 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.

Hais txog qhov no, koj yuav tau txais hluav taws xob los ntawm cov hlau nplaum li cas?

Sib nqus teb tuaj yeem siv rau ua hluav taws xob 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 cov hluav taws xob tam sim no. Hluav taws xob generators yeej tseem ceeb hloov kinetic zog (lub zog ntawm kev txav) mus rau hauv hluav taws xob zog.

Puas muaj lub zog pub dawb nrog cov hlau nplaum?

Kev npau suav niaj hnub yog tsim dawb zog los ntawm mus tas li hlau nplaum . Hauv kev muaj tiag hlau nplaum tsuas tuaj yeem tsim cov teb zoo li qub. Tsis tas li ntawd, lawv cov polarity tsis tuaj yeem thim rov qab.
