Shure nenhoroondo

Magnets anogara aripo chikamu chakakosha chehupenyu hwazvino. Ivo vanowanikwa mukati kana kuti vanoshandiswa kuburitsa zvingangoita zvese zvazviri nyore nhasi. Iwo magineti ekutanga asingaperi akagadzirwa kubva kumasikirwo anoitika matombo anonzi lodestones. Matombo aya akatanga kudzidziswa makore anodarika 2500 apfuura nemaChinese uyezve nemaGreek, ivo vakawana dombo kubva mudunhu reMagnetes, kubva pazvakawana zita raro. Kubva ipapo, zvigadzirwa zvemagineti zvakagadziridzwa zvakanyanya uye nanhasi? S chisingagumi zvigadzirwa zvemagineti zvine mazana emazana nguva dzakasimba kupfuura magnets ezvekare. Izwi rekusingaperi magineti rinobva mukugona kwemagneti yekubata yakadzoreredzwa yemagineti mushure mekunge yabviswa kubva kumagetsi. Midziyo yakadaro inogona kunge iine mamwe maginiti akasimba magineti, magero-magneti kana mataira e waya anotaridzwa zvishoma nemagetsi. Kugona kwavo kubata magineti kunovaita kuti vabatsire kubata zvinhu munzvimbo, kushandura magetsi kune simba rekuita uye zvinopesana (motors nemagetsi), kana kubata zvimwe zvinhu zvinounzwa pedyo navo.

Magnet Sarudzo

Magnet kusarudzwa kwese kwese kushandiswa kunofanirwa kufunga nezvekutenderera kwemagineti nemamiriro ekunze. Ikoko kwakakodzera Alnico, saizi yemagineti inogona kuderedzwa kana inogona kuiswa maginiti mushure mekusangana mumagineti kutenderera. Kana ikashandiswa yakazvimiririra yezvimwe zvikamu zvedunhu, senge mune zvekushandisa kuchengetedzeka, iyo inoshanda kureba kusvika pahupamhi diji (inoenderana nerevheti coefferate) inofanira kunge iri huru zvakakwana kuita kuti magineti isashande pamusoro pebvi mune yechipiri quadrant demagnetization curve. Nezvekushandisa zvakaoma, Alnico magnets anogona kuve akaganhurirwa kune yakatangwa chiratidzo flux density kukosha.

Icho chigadzirwa-chakaderera coercivity ndiko kunzwa kune demagnetizing mhedzisiro nekuda kwekunze magineti, kushamiswa, uye tembiricha yekushisa. Kwekushandisa kwakakomba, maAlnico magneti anogona kuve nekugadziriswa kupisa kudzikisira izvi zvigadziro Pane makosi mana ezvekutengesa ezvino magnets, imwe neimwe zvichienderana nekuumbwa kwavo kwezvinhu. Mukati mega yega yega kune mhuri yemakiredhi ine yavo yemagineti zvinhu. Aya makirasi akajairika ndeaya:

  • Neodymium Iron Boron
  • Samarium Cobalt
  • zvedongo
  • Alnico

NdFeB neSmCo pamwe chete vanozivikanwa seRare Earth magneti nekuti iwo ese ari maviri akaumbwa nezvinhu kubva kuRare Earth boka rezvinhu. Neodymium Iron Boron (general composition Nd2Fe14B, inowanzo pfupiswa kuNdFeB) ndiyo yazvino kutengesa kuwedzera kumhuri yemazuva ano yemagineti zvinhu. Pakupisa kwemakamuri, NdFeB magneti anoratidza iwo epamusoro masimba ezvigadzirwa zvemagineti. Samarium Cobalt inogadzirwa mumanyorerwo maviri: Sm1Co5 uye Sm2Co17 - inowanzonzi mhando dzeSmCo 1: 5 kana SmCo 2:17. 2: 17 mhando, dzakakwira Hci zvimiro, zvinopa hukuru hwekugadzikana kupfuura iwo 1: 5 mhando. Ceramic, inozivikanwawo seFerrite, magnets (general composition BaFe2O3 kana SrFe2O3) yakashambadzirwa kubva kuma1950s uye iri kuramba ichishandiswa zvakanyanya nhasi nekuda kwemutengo wavo wakaderera. Iyo yakakosha fomu yeCeramic magineti ndeye "Inochinjika" zvinhu, zvakagadzirwa nekusunga Ceramic powder mune inoshanduka binder. Alnico magnets (general composition Al-Ni-Co) yakatengeswa kuma 1930 uye achiri kushandiswa zvakanyanya nanhasi.

Izvi zvinoshandiswa zvinoturikidzana huwandu hwezvivakwa zvinogara zvakasiyana siyana zvekushandisa. Izvi zvinotevera kupa chinangwa chakakura asi chinoshanda chechinhu chinofanira kufungwa pakusarudza chakakodzera chinyorwa, giredhi, chimiro, uye saizi yemagineti kune rimwe basa. Chati iri pazasi inoratidza chaiwo maitiro ezvinyorwa zvakakosha zvemakiredhi akasarudzwa ezvivakwa zvakasiyana siyana zvekuenzanisa. Iyi tsika ichakurukurwa zvakadzama muzvikamu zvinotevera.

Magnetizing

Magineti anogara aripo anopihwa pasi pemamiriro maviri, Magnetized kana isina maginiti, haawanzo kuvezwa polarity wawo. Kana mushandisi achida, tinokwanisa kuisa mucherechedzo nenzira dzakabvumiranwa pane. Kana uchirongedza kurongeka, mushandisi anofanira kuzivisa mamiriro ekupa uye kana mucherechedzo we polarity uri madikanwa.

Iyo shamba yemagineti yemagneti isingagumi inoenderana neyekusingaperi magineti rudzi rudzi uye simba rayo rekumanikidza. Kana iyo magineti inoda magnetization uye demagnetization, ndapota taura nesu uye tibvunze isu maitiro.

Pane nzira mbiri dzekurongedza magineti: DC munda uye dhizaini yemagineti.

Pane nzira nhatu dzekudzikisa magineti: demagnetization nekupisa inzira yakakosha yekuita. demagnetization mumunda we AC. Demagnetization mumunda weDC. Izvi zvinobvunza yakasimba kwazvo magineti uye yakakwirira demagnetization hunyanzvi.

Nheyo yekuchengetedza yezve kushanda kwemaoko

1. Magneti anogara narinhi magneti ane simba magineti inokwezva iyo iron nezvimwe zvinhu zvemagineti zvakavakomberedza zvakanyanya. Mumamiriro ezvinhu akajairika, iye anoshanda maneja anofanirwa kuve anongwarira kuti asakuvara. Nekuda kwesimba remagineti yakasimba, magineti makuru ari padyo navo anotora njodzi yekukuvara. Vanhu vanogara vachigadzirisa magneti aya zvakasiyana kana necheni. Mune ino kesi, isu tinofanirwa kushambadzira magurovhinzi ekudzivirira ari kushanda.

2. Mune mamiriro ezvinhu aya emagetsi ane simba, chero chinhu chine musoro chemagetsi nemamita ekuedzwa anogona kuchinjwa kana kukuvara. Ndokumbira kuti uone kuti komputa, inoratidza uye magidhiya, sengeti maginiti, magineti tepi uye vhidhiyo rekodhi tepi nezvimwe, zviri kure nezvinhu zvakagadziriswa, taura zviri kure kupfuura 2m.

3. Kubatana kwemasimba anokwezva pakati pemagneti mairi asingaperi kunounza kupenya kukuru. Naizvozvo, zvinhu zvinopisa kana zvinoputika hazvifanirwe kuiswa zvakavakomberedza.

4. Kana iyo magineti ichinge yaratidzwa kune hydrogen, zvinorambidzwa kushandisa magnets asingaperi pasina dziviriro coating. Icho chikonzero ndechekuti iyo sorption yehydrogen ichaparadza iyo micostosition yemagineti uye ichitungamira pakugadziriswa kwemasimba emagineti. Nzira chete yekudzivirira nayo magineti zvinobudirira ndeyekusungira maginiti mune imwe nyaya uye kuisimbisa.
