NdFeB magineti, inozivikanwawo seneodymium magineti, ari pakati pemagineti akasimba uye anoshandiswa zvakanyanya pasi rose.Izvo zvinogadzirwa kubva musanganiswa we neodymium, iron, uye boron, izvo zvinoguma mune simba remagineti simba.Nekudaro, senge chero imwe magineti, NdFeB magineti anotapukirwa nedemagnetization.Muchikamu chino, tichakurukura zvinhu zvikuru zvinokanganisa demagnetization yeNdFeB magineti.
Tembiricha ndechimwe chezvinhu zvekutanga izvo zvinogona kukonzera demagnetization muNdFeB magineti.Magineti aya ane ayakanyanya kupisa tembiricha, kupfuura izvo vanotanga kurasikirwa nemaitiro avo emagetsi.Iyo tembiricha yeCurie ndiyo poindi iyo iyo magineti inopinda shanduko yechikamu, zvichitungamira kudonha kwakakosha mumagineti yayo.Kune magineti eNdFeB, tembiricha yeCurie inenge 310 degrees Celsius.Saka, kushanda magineti patembiricha iri padyo kana pamusoro peiyi muganhu kunogona kutungamirira ku demagnetization.
Chimwe chinhu chakakosha chinokanganisa demagnetization yeNdFeB magineti ndeyekunze remagineti.Kufumura magineti kune yakasimba inopikisa magineti inogona kuita kuti irasikirwe nemagnetization.Ichi chiitiko chinozivikanwa se demagnetizing.Simba uye nguva yemunda wekunze inoita basa rakakosha mukuita demagnetization.Naizvozvo, zvakakosha kubata NdFeB magineti nekungwarira uye kudzivirira kuaisa kune yakasimba magineti minda inogona kukanganisa yavo magineti.
Corrosion zvakare chinhu chakakosha chinogona kutungamira kune demagnetization yeNdFeB magineti.Aya magineti anogadzirwa kubva kune esimbi alloys, uye kana akafumurwa hunyoro kana mamwe makemikari, anogona kukanganisa.Corrosion inoderedza kusimba kwechimiro chegineti uye inogona kukonzera kurasikirwa kwesimba rayo remagineti.Kudzivirira izvi, machira akadai se nickel, zinc, kana epoxy anowanzo shandiswa kuchengetedza magineti kubva kune hunyoro uye zvinoparadza zvinhu.
Mechanical stress ndechimwe chinhu chinogona kukonzera demagnetization muNdFeB magineti.Kunyanya kudzvinyirira kana kukanganisa kunogona kukanganisa kurongeka kwemagineti mukati megineti, zvichikonzera kudzikira kwesimba rayo remagineti.Naizvozvo, zvakakosha kubata magineti eNdFeB nekungwarira kudzivirira kushandisa simba rakawandisa kana kuzviisa pasi pekukasira.
Chekupedzisira, nguva pachayo inogona zvakare zvishoma nezvishoma kukonzera demagnetization muNdFeB magineti.Izvi zvinozivikanwa sokuchembera.Nekufamba kwenguva, iyo magineti zvimiro zvemagineti zvinogona kudzikira nekuda kwezvinhu zvakasiyana-siyana sekuchinja kwekushisa, kuratidzwa kune ekunze magineti, uye kushushikana kwemagetsi.Kudzikamisa mhedzisiro yekuchembera, kugara uchiyedza uye kutarisa kweiyo magineti zvimiro zvinokurudzirwa.
Mukupedzisa, zvinhu zvakati wandei zvinogona kukanganisa demagnetization yeNdFeB magineti, kusanganisira tembiricha, ekunze magineti minda, ngura, kushushikana kwemagetsi, uye kuchembera.Nekunzwisisa uye kunyatso gadzirisa zvinhu izvi, zvinokwanisika kuchengetedza yakasimba magineti zvimiro zveNdFeB magineti uye kurebesa hupenyu hwavo.Kubata kwakaringana, kudzora tembiricha, uye dziviriro kubva kunzvimbo dzine ngura zvinhu zvakakosha mukuchengetedza kushanda kwemagneti.
