Kurva demagnetisasi, utawa kurva BH minangka kuadran kapindho histeresis kanggo bahan magnetik keras kalebu magnet bumi langka. Iki menehi informasi babagan karakteristik magnetik magnet, kalebu kekuatan medan magnet lan resistensi kanggo demagnetize. Utamane kurva ing suhu dhuwur nyedhiyakake referensi penting kanggo para insinyur kanggo ngetung lan ngerteni materi magnet lan bahan sing cocog kanggo nyukupi syarat kerja. Mulane kita nyiapake kurva demagnetisasi ing sawetara suhu kerja sing dhuwur kanggo magnet Neodymium sintered lan magnet Samarium Cobalt ing ngarep saben kelas sing kasedhiya. Mangga klik saben sel kanggo kurva demagnetisasi.
