Ko te Ferrite he waikura whakarewa o te koranu ferrous. Mō te hiko, he nui ake te ātete o ngā ferrite i ngā hanganga koranu whakarewa taketake, ā, he āhuatanga dielectric anō hoki ō rātou. He iti te pūngao aukume mō ia rōrahi o te ferrite. Ina kohia te auau teitei, he iti te pūngao aukume mō ia rōrahi o te ferrite. He iti hoki te kaha o te (Bs) (1/3~1/5 noa iho o te rino parakore), e whakawhāiti ana i te whānuitanga o ngā kōwhiringa me te whānuitanga o ngā hiahia, ā, ka taea te whakamahi whānui i roto i ngā tono aukume kaha noa i roto i ngā mara rerekē.
Ka whakakoihia te Ferrite mai i ngā waikura rino me ētahi atu kai. I te nuinga o te wā, ka taea te wehewehe ki ngā momo e toru: te ferrite tuturu, te ferrite ngohengohe me te ferrite gyromagnetic.
Ko te ferrite aukume tuturu e kiia ana hoki ko te aukume ferrite, koinei te aukume pango iti e kitea ana e tātou. Ko ōna rauemi matua ko te waikura rino, te barium carbonate, te strontium carbonate rānei. I muri i te aukumetanga, he tino teitei te kaha o te papa aukume toenga, ā, ka taea te pupuri i te papa aukume toenga mō te wā roa. He mea whakamahi noa hei rauemi aukume tuturu. Hei tauira: ngā aukume kaikorero.
Ka whakaritea, ka whakakāhia hoki te ferrite ngohengohe mā te waikura ferric me tētahi, ētahi atu waikura whakarewa rānei (hei tauira: te waikura nickel, te waikura konutea, te waikura manganese, te waikura konupora, te waikura barium, te waikura strontium, me ētahi atu). Ka kiia he aukume ngohengohe nā te mea ina ngaro te papa aukume aukume, he iti noa iho, he kore rānei he papa aukume e toe ana. He tikanga tēnei hei koiri ārai, hei matua rānei o te whakawhiti auau waenga. He tino rerekē tēnei i te ferrite tuturu.
Ko te ferrite gyromagnetic e pā ana ki tētahi rauemi ferrite me ngā āhuatanga gyromagnetic. Ko te gyromagnetism o ngā rauemi aukume e pā ana ki te āhuatanga e horapa ana te papa o te polarization o tētahi ngaru hiko polarized papa-papa i roto i tētahi ahunga i raro i te mahi a ngā papa aukume DC e rua e poutū ana, me ngā papa aukume ngaru hiko. Kua whānuitia te whakamahinga o te ferrite gyromagnetic i roto i te mara o te whakawhitiwhiti kōrero ngaruiti. E ai ki te momo tioata, ka taea te wehewehe i te ferrite gyromagnetic ki te momo spinel, te momo garnet me te momo magnetoplumbite (momo hexagonal).
He whānuitia te whakamahinga o ngā rauemi aukume, ā, ka taea te whakamahi i roto i ngā taputapu hiko-oro, ngā waea whakawhitiwhiti kōrero, ngā mita hiko, ngā motuka, tae atu ki ngā wāhanga mahara, ngā wāhanga ngaruiti, me ētahi atu. Ka taea te whakamahi hei hopu i ngā rīpene mōhiohio reo, waiata, me ngā whakaahua, ngā taputapu rokiroki aukume mō ngā rorohiko, me ngā kāri aukume mō ngā tiikiti eke pāhihi me te utu utu. Ko ngā mea e whai ake nei e arotahi ana ki ngā rauemi aukume e whakamahia ana i runga i te rīpene aukume me te kaupapa mahi.
