Ntchito: NdFeB mphete chimagwiritsidwa ntchito dzenje galimoto chikho, zingalowe zotsukira galimoto, tsitsi chowumitsira galimoto, zokuzira mawu ndi madera ena.Mu ntchito galimoto, ndi chofunika kwambiri pa maginito geometric dimension ndi maginito katundu, kulolerana osachepera akhoza kukhala mkati 0-0.03mm. Mu ntchito zokuzira mawu, maginito nthawi zambiri ndi ❖ kuyanika Zn, yobereka pansi un-magnetized chikhalidwe, maginito kalasi ngati N, M ndi H mndandanda kalasi, nthawi zambiri zokuzira mawu maginito safuna apamwamba kalasi. Ntchito ina ndi zodzikongoletsera msika, tikupereka mamiliyoni zidutswa mphete maginito kwa makasitomala athu padziko lonse lapansi, maginito ntchito ma CD bokosi, axial magnetized. kapena multipole axial maginito ngati 2 kapena 4 mizati, osati kwa maginito koyera, ndifenso avaialbe kwa ena maginito msonkhano.
Zogulitsa makonda: Maginito athu a mphete amatha kusinthidwa kuchokera ku 3mm-200mm m'mimba mwake, 1mm-150mm mkati mwake, makulidwe kuchokera ku 1mm-70mm. Amafunikanso zokutira nthawi zambiri, monga NiCuNi, Zn, Epoxy ndi zina zotero.
