Demagnetization Nkhaus

Demagnetization nkhaus, lossis BH nkhaus yog qhov thib ob quadrant ntawm hysteresis rau cov khoom sib nqus nyuaj nrog rau cov hlau nplaum hauv ntiaj teb tsis tshua muaj. Nws muab cov ntaub ntawv hais txog cov yam ntxwv sib nqus ntawm cov hlau nplaum, suav nrog lub zog sib nqus ntawm lub zog loj thiab kev tawm tsam kom demagnetize. Tshwj xeeb yog qhov nkhaus ntawm qhov kub siab muab qhov tseem ceeb siv rau cov engineers los laij thiab tshawb pom cov khoom siv hlau nplaum tsim nyog thiab qib kom tau raws li lawv xav tau ua haujlwm. Yog li no peb npaj koj demagnetization nkhaus nyob rau ntau qhov chaw ua hauj lwm siab rau sintered Neodymium hlau nplaum thiab Samarium Cobalt hlau nplaum fore txhua qib muaj. Thov nyem rau txhua lub xov tooj rau nws cov demagnetization curves feem.
