Demagnetization curve, po'o le BH curve o le lua lona lua o hysteresis mo mea maneta malo e aofia ai maneta e le masani ai. E maua ai fa'amatalaga e uiga i uiga fa'amaneta o se maneta, e aofia ai le malosi o le fa'amaneta ma le tete'e i le demagnetize. Aemaise lava le pi'o i le vevela maualuga e maua ai le fa'amatalaga taua mo inisinia e fa'atatau ma su'e mea maneta talafeagai ma togi e fa'afetaui ai latou mana'oga faigaluega. O le mea lea matou te saunia ai oe pupuni fa'amaneta i le tele o vevela galue maualuga mo maneta Neodymium sintered ma Samarium Cobalt maneta i luma vasega avanoa taitasi. Fa'amolemole kiliki sela ta'itasi mo ona pupuni fa'amaneta.
