Taw qhia ntawm Pobzeb Magnet (Magnetic Vuas)

Taw qhia ntawm pobzeb hlau nplaum (sib nqus pobzeb)

Hais txog cov hlau nplaum, lub vev xaib qhia cov hlau nplaum NdFeB muaj zog dua thiab cov hlau nplaum tshwj xeeb. Muaj qee qhov kev qhia txog cov nplais zoo li cov hlau nplaum (sib nqus vuas). Niaj hnub no, cov nplais zoo li cov hlau nplaum yuav qhia tshwj xeeb.

Hais txog cov pobzeb zoo li cov hlau nplaum, feem ntau siv yog NdFeB pobzeb-zoo li cov hlau nplaum, samarium-cobalt pobzeb-zoo li cov hlau nplaum, sib txuas NdFeB cov vuas sib nqus, thiab ferrite pobzeb-zoo li cov hlau nplaum, uas yog siv hauv cov motors. Saum toj no (raws li qhia hauv daim duab hauv qab no), puas yog daim ntawv thov ntawm cov nplais zoo li cov hlau nplaum siv dav?

NdFeB pobzeb zoo li cov hlau nplaum loj npaum li cas tuaj yeem tsim tau?
Cov lus qhia tshwj xeeb ntawm cov vuas sib nqus siv hauv cov khoom siv mining kuj tseem loj heev, thiab muaj ntau pua tus neeg sab nrauv R. Peb kuj tuaj yeem ua qhov loj me me. Yog tias nws loj dhau, nws yuav tsum tau qhib pwm kom tiav.

Thaum cov neeg siv khoom xaiv cov pobzeb-zoo li tus hlau nplaum (sib nqus pobzeb), ntxiv rau qhov ntev: R sab nraud, r puab txoj kab uas hla, L ntev, H qhov siab, thiab A lub kaum sab xis, lawv kuj yuav tsum tau muab cov ntaub ntawv xws li txheej txheej, kev taw qhia magnetization, thiab kam rau ua.

Feem ntau hais lus, zinc plating thiab npib tsib xee plating yog feem ntau, thiab cov kev taw qhia ntawm magnetization feem ntau yog radial, los ntawm sab hauv mus rau sab nraud los yog sab nraud mus rau sab hauv, thiab axial magnetization kuj siv tau.
