Round mphete Block Arc Permanent Ferrite Magnet
Mafotokozedwe Akatundu
Maginito a Ferrite (omwe amadziwikanso kuti maginito a ceramic) ndi maginito osatha.
Iwo ali makamaka Strontium zochokera (SrFe2O3), opangidwa ndi Strontium Carbonate zowonjezera kuonjezera zisudzo kuchokera zakale Barium zochokera (BaFe2O3).
Mphamvu yawo yabwino yokakamiza imachokera ku crystal anisotropy ya strontium iron oxide. Komabe, magawo a isotropic amathanso kupangidwa pomwe maginito osavuta komanso osavuta amitundu yambiri amafunikira.
Potengera mawonekedwe amagetsi, resistivity ya ferrite ndi yayikulu kwambiri kuposa yachitsulo ndi aloyi maginito, komanso imakhala ndi ma dielectric apamwamba.
Mphamvu ya maginito ya ferrite imawonetsanso kutulutsa kwakukulu pama frequency apamwamba.
Ferrite siwoyendetsa ndipo imakhala ndi mphamvu yolimbana ndi dzimbiri, zidulo, mchere, ndi mafuta. Mawonekedwe ambiri ndi osavuta, monga ma disc, midadada, masilindala, mphete, ndi ma arcs.
Maginito a Ferrite amagwiritsidwa ntchito kwambiri m'zaka makumi angapo zapitazi, monga zokuzira mawu, ma mota, ndi ma jenereta.
