Demagnetization Curves

Demagnetization nkhaus, los yog BH nkhaus yog qhov thib ob quadrant ntawm hysteresis rau cov khoom sib nqus nyuaj nrog rau cov hlau nplaum tsis tshua muaj hauv ntiaj teb.Nws muab cov ntaub ntawv hais txog cov yam ntxwv sib nqus ntawm cov hlau nplaum, suav nrog lub zog hlau nplaum thiab kev tiv thaiv kom demagnetize.Tshwj xeeb tshaj yog qhov nkhaus ntawm qhov kub thiab txias muab cov ntaub ntawv tseem ceeb rau cov engineers los xam thiab nrhiav cov khoom siv hlau nplaum tsim nyog thiab qib kom tau raws li lawv txoj haujlwm.Yog li no peb npaj koj demagnetization nkhaus ntawm ob peb lub siab ua haujlwm kub rau sintered Neodymium hlau nplaum thiab Samarium Cobalt hlau nplaum rau txhua qib muaj.Thov nias txhua lub xov tooj rau nws cov demagnetization nkhaus raws.
