Koub demagnetization, oswa koub BH se dezyèm kadran isterèz pou materyèl mayetik difisil ki gen ladan leman latè ra. Li bay enfòmasyon sou karakteristik mayetik yon leman, ki gen ladan fòs nan jaden mayetik ak rezistans nan demagnetize. Espesyalman koub la nan tanperati ki wo bay referans enpòtan pou enjenyè yo kalkile epi chèche konnen materyèl leman ki apwopriye ak klas yo satisfè kondisyon travay yo. Se poutèt sa, nou prepare w koub demagnetization nan plizyè tanperati k ap travay segondè pou leman Neyodim sintered ak leman Samarium Cobalt anvan chak klas ki disponib. Tanpri klike sou chak selil pou koub demagnetization li yo respektivman.
