Codsiga: giraanta NdFeB waxaa si weyn loogu isticmaalaa matoorka koobka bannaan, mashiinka nadiifiyaha vacuum, mashiinka timaha qalajiyaha, cod-baahiyaha iyo meelo kale.Codsiyada mootada, waxay leedahay shuruudo aad u sarreeya oo ku saabsan cabbirka joomatari ee magnetka iyo hantida magnetka, dulqaadka ugu yar wuxuu noqon karaa 0-0.03mm. Codsiyada cod-baahiyaha, magnetka ayaa sida caadiga ah leh daahan Zn, gaarsiinta xaalad aan-magnetized ahayn, darajada magnet sida N, M iyo H taxanaha darajada, sida caadiga ah sameecado magnet uma baahna darajo sare. Codsiga kale waa suuqa isqurxin, waxaan siinaynaa malaayiin xabbadood giraanta magnetka our macaamiisheena adduunka oo dhan, magnets waxaa loo isticmaalaa sanduuqa baakadaha, axial magnetized ama axial multipole magnetized sida 2 ama 4 tiirarka, oo ma aha oo kaliya magnet saafi ah, waxaan sidoo kale avaialbe for qaar ka mid ah shirka magnetka.
Alaabooyinka la habeeyey: Magnet giraantayada waxaa laga beddeli karaa 3mm-200mm dhexroorka dibadda ah, dhexroorka gudaha 1mm-150mm, dhumucdiisuna tahay 1mm-70mm.Waxa kale oo ay u baahan tahay daahan inta badan, sida NiCuNi, Zn, Epoxy iyo wixii la mid ah.
