Feem ntau siv rau ob qho chaw rau kev hloov pauv zog thiab kev ua cov ntaub ntawv

Hauv kev lag luam fais fab, feem ntau yog nyob rau hauv lub zog magnetic siab, muaj qhov induction magnetic siab thiab qis core poob ntawm cov hlau. Hauv kev lag luam electronics, feem ntau yog nyob rau hauv qis lossis nruab nrab alloy muaj qhov permeability siab magnetic thiab qis coercive force. Ntawm zaus siab, yuav tsum tau ua rau ntawm ib daim nyias nyias lossis alloy siab dua resistivity. Feem ntau nrog daim ntawv lossis daim kab xev.

Cov khoom siv sib nqus mos mos uas pauv rau kev siv, vim yog cov hluav taws xob eddy tam sim no raug tsim tawm hauv cov khoom siv, ua rau poob, qhov me dua qhov tsis kam ntawm cov hlau nplaum, qhov tuab dua, qhov siab dua qhov zaus ntawm lub teb sib nqus hloov pauv, eddy tam sim no poob ntau dua, sib nqus txo ntau dua. Rau qhov no, cov khoom siv yuav tsum tau ua daim ntawv nyias dua (daim kab xev), thiab qhov chaw txheej nrog ib txheej rwb thaiv tsev, lossis siv qee txoj hauv kev rau qhov chaw los ua ib txheej oxide rwb thaiv tsev, xws li cov hlau nplaum feem ntau siv magnesium oxide electrophoresis txheej.

Hlau-nickel alloy feem ntau siv rau hauv kev hloov pauv magnetic teb, feem ntau yog rau yoke hlau, relay, me me fais fab transformers thiab magnetically shielded.

Kev tiv thaiv hlau nplaum permalloy yuav tsum ua li cas: Yuav kom tiv thaiv kev cuam tshuam ntawm lub zog sib nqus sab nraud, feem ntau hauv CRT, ib qho chaw tsom mus rau sab nraud CRT electron beam ntxiv rau lub zog sib nqus, koj tuaj yeem ua lub luag haujlwm ntawm kev tiv thaiv hlau nplaum.
