Ma muli o ka lōʻihi, ʻaʻole i hoʻokomo ʻia i loko o ka hihia non-magnet, ua maʻalahi ka axial magnetized cylinder magnet i ka poʻe e hopu me nā manamana lima a laila kūʻai nui ʻia a hoʻohana ʻia e like me ka noi hoʻokipa maʻamau e ka poʻe maʻamau i ke ola o kēlā me kēia lā. Ua kapa ʻia ʻo ia he cylinder rare earth magnet, cylinder Neodymium magnet, NdFeB cylinder magnet, etc.
ʻO ka mea maʻamau, hoʻopuka pololei ʻia ka neodymium cylinder magnet i hoʻopaʻa ʻia ma o ka mānoanoa ma ke kaomi ʻana i kahi pahu magnet semi-finished cylinder. He mea maʻalahi a maʻalahi hoʻi ka mīkini ʻana i kahi magnet koʻokoʻo i hoʻopau i ka nui magnet. ʻO ka mea mua, hoʻohana ʻia ka wili coreless e wili i ke anawaena pololei. ʻO ka lua, ʻo ka mānoanoa a i ʻole ke kiʻekiʻe e wili ʻia i ka mokulele i hoʻokahi kiʻekiʻe cylinder magnet i hoʻopau ʻia, a i ʻoki ʻia i nā ʻāpana ʻāpana koʻokoʻo me ke kiʻekiʻe pōkole. Inā lōʻihi loa ke kiʻekiʻe o ka neodymium cylinder magnet hope loa, no ka laʻana he 60 mm a i ʻole nā mea hoʻokalakupua i makemake ʻia, ʻoi aku ka paʻakikī o ke kaomi pololei ʻana i ka mana magnetic kiʻekiʻe. A laila hiki ke hana ʻia a hana ʻia mai nā poloka magnet rectangular.
Ma ʻEulopa a me ʻAmelika, hoʻolako nā ʻoihana he nui i nā kūʻai pūnaewele no nā ana maʻamau o nā magnet Neodymium me nā māka kiʻekiʻe, e like me N40, N42, N45, N52, a me nā mea ʻē aʻe.
