Poʻai Poʻai Poʻai Arc Permanent Ferrite Magnet
Hōʻike huahana
ʻO ka Ferrite Magnet (kahi i ʻike ʻia ʻo ka ceramic magnet ) he magnet mau loa.
Hoʻokumu ʻia lākou ma Strontium (SrFe2O3), i hana ʻia me Strontium Carbonate additive e hoʻonui i nā hana mai ka Barium kahiko (BaFe2O3).
ʻO kā lākou ikaika hoʻoikaika maikaʻi mai ka anisotropy aniani kiʻekiʻe o ka strontium iron oxide. Eia nō naʻe, hiki ke hana ʻia nā ʻāpana isotropic kahi e koi ʻia ai kahi magnetization multi-pole maʻalahi.
Ma ke ʻano o nā hiʻohiʻona uila, ʻoi aku ka nui o ka resistivity o ka ferrite ma mua o nā mea metala a me nā mea kila kila, a ʻoi aku ka kiʻekiʻe o nā waiwai dielectric.
Hōʻike pū nā waiwai magnetic o ka ferrite i ka permeability kiʻekiʻe ma nā alapine kiʻekiʻe.
ʻAʻole conductive ka Ferrite a he kūpaʻa kiʻekiʻe i ka corrosion, nā waikawa, nā paʻakai, a me nā lubricants. He maʻalahi nā ʻano maʻamau, e like me ka disc, blocks, cylinders, apo, arcs.
Hoʻohana mau ʻia nā magnet Ferrite i nā noi like ʻole i nā makahiki i hala aku nei, e like me nā leo leo, nā kaʻa, a me nā mea hana.
