Demagnetizatsiya egri chiziqlari

Demagnetizatsiya egri chizig'i yoki BH egri qattiq magnit materiallar, shu jumladan noyob tuproq magnitlari uchun histerezisning ikkinchi kvadrantidir. U magnitning magnit xususiyatlari, jumladan magnit maydon kuchi va demagnetizatsiyaga qarshilik haqida ma'lumot beradi. Ayniqsa, yuqori haroratdagi egri chiziq muhandislarga ularning ish talablarini qondirish uchun mos magnit materialini va sinfini hisoblash va topish uchun muhim ma'lumot beradi. Shuning uchun biz shu bilan har bir mavjud sinf uchun sinterlangan Neodimiy magnitlari va Samarium kobalt magnitlari uchun bir nechta yuqori ish haroratida demagnetizatsiya egri chiziqlarini tayyorlaymiz. Iltimos, mos ravishda demagnetizatsiya egri chiziqlari uchun har bir katakchani bosing.
