30 Makahiki Hale Kūʻai Hale Hana Barium Ferrite Magnet
ʻO ka Ferrite magnet kahi ʻano magnet mau loa i hana nui ʻia me SrO a i ʻole Bao a me Fe2O3. He mea hana ia i hana ʻia e ke kaʻina hana seramika, me ka loop hysteresis ākea, coercivity kiʻekiʻe a me ka remanence kiʻekiʻe. Ke magnetized ʻia, hiki iā ia ke mālama i ka magnetism mau, a ʻo ka density o ka hāmeʻa he 4.8g/cm3. Ke hoʻohālikelike ʻia me nā magnet mau loa ʻē aʻe, he paʻakikī a palupalu nā magnet ferrite me ka ikehu magnetic haʻahaʻa. Eia naʻe, ʻaʻole maʻalahi ka demagnetize a me ka corrode, maʻalahi ke kaʻina hana a haʻahaʻa ke kumukūʻai. No laila, ʻo nā magnet ferrite ka mea i loaʻa ka hopena kiʻekiʻe loa ma ka ʻoihana magnet holoʻokoʻa a hoʻohana nui ʻia i ka hana ʻoihana.
