Ọkpụkpụ demagnetization, ma ọ bụ usoro BH bụ akụkụ nke abụọ nke hysteresis maka ihe ndọta siri ike gụnyere ihe ndọta ụwa na-adịghị ahụkebe. Ọ na-enye ozi gbasara njirimara magnetik nke ndọta, gụnyere ike ndọta na iguzogide demagnetize. Karịsịa usoro mgbanaka na oke okpomọkụ na-enye ntụaka dị mkpa maka ndị injinia iji gbakọọ ma chọpụta ihe magnetik kwesịrị ekwesị na ọkwa iji mezuo ọrụ ha chọrọ. Ya mere, anyị na-akwado gị usoro demagnetization n'ọtụtụ okpomọkụ na-arụ ọrụ maka magnet Neodymium na Samarium Cobalt magnet tupu ọkwa ọ bụla dị. Biko pịa cell ọ bụla maka akụkụ nke demagnetization ya n'otu n'otu.
