Feem ntau siv nyob rau hauv ob qhov chaw rau lub zog hloov dua siab tshiab thiab cov ntaub ntawv ua
Hauv kev lag luam fais fab, feem ntau yog nyob rau hauv high magnetic teb muaj ib tug high magnetic induction thiab tsawg core poob ntawm alloy. Hauv kev lag luam hluav taws xob, feem ntau ntawm cov khoom siv qis lossis nruab nrab muaj qhov sib nqus permeability siab thiab tsis tshua muaj zog quab yuam. Nyob rau hauv high zaus yuav tsum tau ua nyob rau hauv ib tug nyias strip los yog alloy siab dua resistivity. Feem ntau nrog daim ntawv los yog sawb.
Cov ntaub ntawv sib nqus mos hauv kev sib pauv rau kev siv, vim yog qhov sib nqus sib nqus eddy tam sim no raug ntxias hauv cov khoom, ua rau poob, qhov me me ntawm cov hlau tsis kam, qhov thickness ntau dua, qhov ntau zaus ntawm qhov sib nqus magnetic, eddy. tam sim no poob ntau dua, sib nqus txo ntau dua. Rau qhov no, cov khoom yuav tsum tau ua thinner daim ntawv (kab xev), thiab nto coated nrog ib tug insulating txheej, los yog siv tej yam kev rau saum npoo los tsim ib oxide insulating txheej, xws li alloys feem ntau siv magnesium oxide electrophoresis txheej.
Hlau-nickel alloy feem ntau nyob rau hauv alternating magnetic teb siv, feem ntau yog rau yoke hlau, relay, Me fais fab Transformers thiab Magnetically shielded.
Permalloy magnetic shielding ua: Txhawm rau tiv thaiv kev cuam tshuam ntawm sab nraud magnetic teb, feem ntau hauv CRT, sab nraud CRT electron beam tsom rau seem ntxiv rau cov ntaub thaiv npog sib nqus, koj tuaj yeem ua lub luag haujlwm ntawm cov hlau nplaum tiv thaiv.
