Maneta Fa'amaneta Fa'ata'amilomilo Arc Fa'amau Ferite
Fa'amatalaga o oloa
O le Ferrite Magnet (fa'aigoa o se maneta sima ) o se maneta tumau.
E masani lava ona fa'avaeina le Strontium (SrFe2O3), fa'apipi'i fa'atasi ma le Strontium Carbonate fa'aopoopo e fa'atuputeleina ai fa'atinoga mai le fa'avae o le Barium (BaFe2O3).
O lo latou malosi faʻamalosi lelei e sau mai le anisotropy tioata maualuga o le strontium iron oxide. Ae ui i lea, e mafai foi ona gaosia vaega isotropic pe a manaʻomia se maneta faigofie ma faigofie tele-pole.
E tusa ai ma uiga eletise, o le resistivity o le ferrite e sili atu le tele nai lo le uʻamea ma mea faʻagata maneta, ma e iai foʻi mea e sili atu le dielectric.
O mea fa'amaneta o le ferrite o lo'o fa'aalia ai fo'i le maualuga o le fa'aogaina i laina maualuga.
O le Ferrite e le fa'aosoina ma e maualuga lona tete'e i le pala, acids, masima, ma lubricants. O foliga masani e faigofie, e pei o le disk, poloka, cylinders, mama, ma arcs.
Ferrite maneta e masani ona faʻaaogaina i faʻaoga eseese i le tele o tausaga ua tuanaʻi, e pei o sipika, afi, ma afi afi.
