Ibintu nyamukuru bigira ingaruka kuri demagnetisation ya magnet ya NdFeB

Ubushyuhe nimwe mubintu byibanze bishobora gutera demagnetisation muri magnet ya NdFeB. Izi magneti zifite aubushyuhe ntarengwa bwo gukora, hejuru yabyo batangira gutakaza imiterere ya magneti. Ubushyuhe bwa Curie niho ibintu bya rukuruzi bigenda bihinduka, biganisha ku kugabanuka gukomeye kwa magneti. Kuri magnet ya NdFeB, ubushyuhe bwa Curie ni dogere selisiyusi 310. Rero, gukoresha magnet mubushyuhe hafi cyangwa hejuru yiyi mipaka birashobora kuganisha kuri demagnetisation.

Ikindi kintu cyingenzi kigira ingaruka kuri demagnetisation ya magneti ya NdFeB ni magnetiki yo hanze. Kugaragaza magneti kumurima ukomeye urwanya magnetique birashobora gutuma itakaza magnetisiyasi. Iyi phenomenon izwi nka demagnetizing. Imbaraga nigihe cyumwanya wo hanze bigira uruhare runini mubikorwa bya demagnetisation. Niyo mpamvu, ni ngombwa gukoresha magneti ya NdFeB witonze kandi ukirinda kuyashyira mumashanyarazi akomeye ashobora guhungabanya imiterere ya magneti.

Ruswa nayo ni ikintu gikomeye gishobora kuganisha kuri demagnetisation ya magnet ya NdFeB. Iyi magnesi ikozwe mu byuma bivangwa n'ibyuma, kandi iyo ihuye n'ubushuhe cyangwa imiti imwe n'imwe, irashobora kwangirika. Kwangirika bigabanya uburinganire bwimiterere ya rukuruzi kandi bishobora kuvamo gutakaza imbaraga za rukuruzi. Kugira ngo wirinde ibi, hashyirwaho ibifuniko nka nikel, zinc, cyangwa epoxy kugirango birinde magnesi kutagira ubushuhe nibintu byangirika.

Guhangayikishwa nubukanishi ni ikindi kintu gishobora gutera demagnetisation muri magneti ya NdFeB. Umuvuduko ukabije cyangwa ingaruka birashobora guhungabanya guhuza imiyoboro ya magneti muri magneti, bigatuma imbaraga za rukuruzi zigabanuka. Niyo mpamvu, ni ngombwa gukoresha neza magnet ya NdFeB kugirango wirinde gukoresha imbaraga zikabije cyangwa kuzitera ingaruka zitunguranye.

Ubwanyuma, igihe ubwacyo gishobora nanone gutera buhoro buhoro demagnetisation muri magnet ya NdFeB. Ibi bizwi nko gusaza. Mugihe kinini, imiterere ya magneti ya magneti irashobora kwangirika mubisanzwe bitewe nibintu bitandukanye nkimihindagurikire yubushyuhe, guhura nimirima ya magneti yo hanze, hamwe nihungabana ryimashini. Kugabanya ingaruka zo gusaza, birasabwa kwipimisha buri gihe no kugenzura imiterere ya magneti.

Mu gusoza, ibintu byinshi bishobora kugira ingaruka kuri demagnetisation ya magneti ya NdFeB, harimo ubushyuhe, imirima ya rukuruzi yo hanze, kwangirika, guhangayika, no gusaza. Mugusobanukirwa no gucunga neza ibyo bintu, birashoboka kuzigama imbaraga zikomeye za magneti ya magnet ya NdFeB no kuramba. Gufata neza, kugenzura ubushyuhe, no kurinda ibidukikije byangirika nibintu byingenzi bitekerezwaho mugukomeza imikorere ya rukuruzi.
