Mekhahlelo ea Demagnetization

Mothamo oa Demagnetization, kapa BH curve ke quadrant ea bobeli ea hysteresis bakeng sa lisebelisoa tse thata tsa matla a khoheli ho kenyelletsa le limakete tse sa tloaelehang tsa lefats'e. E fana ka tlhaiso-leseling ka makenete a makenete, ho kenyelletsa matla a matla a khoheli le ho hanyetsa matla a khoheli. Haholo-holo mothinya oa mocheso o phahameng o fana ka ts'upiso ea bohlokoa bakeng sa baenjiniere ho bala le ho fumana lisebelisoa tse nepahetseng tsa makenete le sehlopha ho fihlela litlhoko tsa bona tsa ho sebetsa. Ka hona re u lokisetsa li-demagnetization curves maemong a 'maloa a phahameng a ho sebetsa bakeng sa limakete tsa Neodymium tse sintered le limakete tsa Samarium Cobalt pele ho sehlopha ka seng se fumanehang. Ka kopo tlanya sele ka 'ngoe bakeng sa methapo ea eona ea demagnetization ka tatellano.
