Mpempe Demagnetization

Demagnetization curve, ma ọ bụ BH curve bụ quadrant nke abụọ nke hysteresis maka ihe magnetik siri ike gụnyere ihe ndị dị egwu n'ụwa. Ọ na-enye ozi gbasara njirimara magnet nke magnet, gụnyere ike ndọta na iguzogide demagnetize. Karịsịa usoro dị elu dị elu na-enye nkọwa dị mkpa maka ndị injinia iji gbakọọ ma chọpụta magnet kwesịrị ekwesị na ọkwa iji mezuo ọrụ ha chọrọ. Ya mere, anyị si ugbu a kwadebe gị ntụgharị demagnetization n'ọtụtụ n'ọtụtụ na-arụ ọrụ dị elu maka magnetik Neodymium na Samarium Cobalt magnets na ọkwa ọ bụla dị. Biko pịa sel nke ọ bụla maka akụkụ ya demagnetization n'otu n'otu.
