Kuumbwa kwemagineti ekugadzira kunobva pane magnetization yesimbi dzakasiyana-siyana, zvichienderana nezvinodiwa.Magineti inosvika (inobata) chinhu chine magineti chinoitwa kune rumwe rutivi kuti chigadzire danda rezita uye kune rumwe rutivi kugadzira danda rezita.
Classification of magineti A. Temporary (soft) magineti.Zvinoreva: Magnetism inguva pfupi uye inonyangarika kana magineti abviswa.Muenzaniso: zvipikiri zvesimbi, simbi yakagadzirwa
Classification of magineti B. Permanent (yakaoma) magineti.Zvinoreva: Magnetism inogona kuchengetwa kwenguva yakareba mushure memagnetization.Muenzaniso: chipikiri chesimbi
Ruzivo rwuri pamusoro rwakapfupikiswa sezvizvi: maererano nemusimboti we electromagnetic induction, ikozvino yakasimba inogona kugadzira simba remagineti, uye kushandiswa kwesimba remagineti kuita magineti ferromagnetic zvinhu, uye nekuda kweakasiyana magineti maitiro ezvinhu zvakasiyana, zvimwe. zvinhu zviri nyore kuita magineti, uye hazvisi nyore kurasikirwa nemagineti (magineti kurasikirwa), inogona kuchengetedza iyo magineti kwenguva yakareba.Magnetizing ichi chidimbu chechinhu chinoburitsa magineti.Magineti akaomarara ane magineti ane magnetizing muchina.
Zvinoenderana nemusimboti weelectromagnetic induction, magetsi emagetsi anogona kugadzira Magnetic munda unoshandisa munda wakasimba kuita magineti yakaoma Magnetic chinhu.AMagnetic Material, inowanzonzi magineti.Izvo chaizvo zvinhu zvakati wandei zvakasiyana: magineti akajairwa, senge anoshandiswa mune yakajairika gudzanzwi, ndeye ferromagnetic.Iyo inoshandiswa mukugadzira simbi inopisa yakakungurutswa kubva musimbi billet inokunguruka kubva pamusoro pesimbi chiyero (ndiro yakaumbwa nesimbi oxide), mushure mekubvisa kusachena, kupwanya, kuwedzera hushoma hwezvimwe zvinhu pane simbi mold ye extrusion kugadzira, uye ipapo (hydrogen) mukuderedza kunyura kwechoto, ita imwe oxide kuderedza mu ferrite, kutonhora, uye wozoisa exciter mune magnetization.
Permanent Magnetszviri nani pane izvi: Permanent Magnet isimbi, iyo inosanganisira kunyanya yepamusoro yenickel, kuwedzera kune iron.Iyo inowanzonyungudutswa nepakati frequency choto chemagetsi (chete 100 kg pachoto), ichikanda kuumbwa, nekuti imwe yendege yayo ine chaizvo zvinodiwa, kazhinji kushandisa grinder kugaya kugadzirisa.Uye ipapo magnetized mune chigadzirwa.Iyi mhando yemagineti inoshandiswa mumarudzi ese emamita emagetsi.Zviri nani magineti zvinhuNdfeb Neodymium Magnet.Izvo zvinhu zvine zvisingawanzo pasi zvinhu neodymium, iron uye boron.
Kugadzirwa kunogadzirwa nenzira yeyakaoma alloy: mushure mePulverizing - Kusanganisa - Kuumba - Sintering - Kupedzisa - Magnetization.Rudzi urwu rwesimba remagineti rakakwirira, kuita kuri nani, mutengo unodhura.Inoshandiswa chete munyaya yezvigadzirwa.Iyo inotsika mota rotor muwachi yemagetsi ndiyo magineti levitation chitima chinofanira kushandisa iyi magineti.
Ferrite zvechigarire magineti zvinhu ndezvi: strontium-ferrite zvechigarire magineti zvinhu uye barium ferrite zvechigarire magineti zvinhu, izvo zvine isotropic uye anisotropic mapoinzi, mutauri magineti anowanzoshandiswa ferrite zvachose magineti zvinhu;Iyo huru yesimbi yekusingaperi magineti zvinhu ndeyeAlnico magneticuye zvisingawanzo pasi zvechigarire magineti zvinhu.Iwo magineti epasi asingawanzo akapatsanurwazve kuitaSmco Magnetsuye NdFeb Magnets.Rare Earth zvachose magineti zvinhu zvinogadzirwa nehupfu metallurgy process.
