Kushandiswa kweElectromagnetic Induction muTekinoroji Yemazuva Ano
Kupinza kwemagetsi nemagetsi chinhu chakawanikwa naMichael Faraday muna 1831, umo simba remagineti rinoshanduka rinogadzira simba remagetsi (EMF) muconductor. Nheyo iyi inotsigira zvakawanda zvezvishandiso zvetekinoroji zvatinoshandisa zuva nezuva, kubva kumajenareta emagetsi kusvika kumidziyo yemagetsi. Chinyorwa chino chichaongorora mashandisirwo akasiyana-siyana ekuisa magetsi nemagetsi mutekinoroji yemazuva ano, kutsanangura mashandiro ayo, uye nei chiitiko ichi chakakosha pakufambira mberi kwetekinoroji.
Nheyo yeKugadzirwa kweElectromagnetic
Kupinza kwemagetsi mumagetsi kunogona kutsanangurwa kuburikidza nemutemo waFaraday nemutemo waLenz. Mutemo waFaraday unoti emf inokonzerwa neconductor inoenderana zvakananga nehuwandu hwekuchinja kweflux yemagineti kuburikidza nayo. Mutemo waLenz unotiwo kutungamira kweinduced current kucharamba kuchipesana nekuchinja kweflux yemagineti yakakonzera.
Pamasvomhu, emf induced (\(\mathcal{E}\)) inogona kuratidzwa seizvi:
\[ \masvomhu{E} = -\frac{d\Phi_B}{dt} \]
Di mana:
– \(\Phi_B\) ndiyo magnetic flux,
– \(d\Phi_B/dt\) ndiyo mwero wekuchinja kwesimba remagineti.
Kushandiswa muTekinoroji Yemazuva Ano
1. Jenareta yemagetsi
Majenareta emagetsi ndeimwe yenzira dzakananga uye dzakakosha dzekushandisa electromagnetic induction. Majenareta anoshandura simba remakanika kuita simba remagetsi achishandisa musimboti we electromagnetic induction.
Mujenareta, simba remagineti rinotenderera rakatenderedza waya, kana kuti coil rinotenderera mukati mesimba remagineti. Kuchinja-chinja kwemagineti kuburikidza necoil kunoburitsa emf, iyo inozoburitsa magetsi. Majenareta anoshandiswa mumafekitori emagetsi kugadzira magetsi atinoshandisa zuva nezuva.
2. Transformator
Transformer mudziyo unoshandiswa kushandura voltage ye alternating current (AC) mumagetsi. Ine ma coil maviri ewaya (primary coil ne secondary coil) akabatanidzwa ne magnetic core.
Kuchinjana kwemagetsi mu coil yekutanga kunogadzira simba remagineti rinochinja, iro rinozokonzera emf mu coil yechipiri zvichienderana nemutemo waFaraday. Chiyero chehuwandu hwekutenderera pakati pe coil yekutanga neyechipiri chinosarudza chiyero chekuchinja kwevoltage. Matransformer akakosha mukugoverwa kwemagetsi, zvichiita kuti voltage ikwidzwe kuti iendeswe kure uye idzikiswe kuti ishandiswe zvakachengeteka mudzimba nemaindasitiri.
3. Mota yeMagetsi
Mamota emagetsi anoshanda zvakasiyana nemajenareta. Mumota, magetsi anoyerera nepa coil mumunda wemagineti, zvichigadzira simba remakanika kuburikidza nemutemo waLorentz, uyo unokonzera kuti coil itenderere. Mamota emagetsi anoshandiswa mumhando dzakasiyana-siyana, kubva kumafeni kusvika kumotokari dzemagetsi.
4. Induktor
Inductor chinhu chemagetsi chakagadzirirwa kuva neinductance chaiyo uye chinoshandiswa kuchengetedza simba mumunda wemagineti. Chinoshandiswa zvakanyanya mumaseketi emagetsi, akadai semafirita, maoscillator, uye ma voltage regulators. Mumafirita, ma inductor anoshanda pamwe chete nema capacitor kuchenesa mamwe ma frequency kubva kuchiratidzo chemagetsi.
5. Chitofu cheInduction
Maheater einduction anoshandisa musimboti we electromagnetic induction kune zvinhu zvinofambisa kupisa. Kuchinjana kwemagetsi kunoyerera kuburikidza ne induction coil kunoita kuti simba remagineti rive rinochinja, iro rinozokonzera ma eddy currents muzvinhu zvinopisa. Aya ma eddy currents anogadzira kupisa nekuda kwekusasimba kwechinhu chacho. Maheater einduction anoshandiswa mumaindasitiri akasiyana-siyana, kusanganisira welding, simbi inonyungudutsa, uye mamwe maitiro ekugadzira.
6. MaSensor nemaTransducer
MaSensor nematransducer anowanzo shandisa musimboti we electromagnetic induction kuona shanduko dziri kuitika munharaunda. Semuenzaniso, ma sensor ane linear ne rotary position anoshandisa coils nemagineti kuona mafambiro nenzvimbo nekuyera shanduko mu magnetic flux. Iyi tekinoroji inoshandiswa mu navigation systems, industrial process control, uye medical devices.
7. Zvishandiso zvekuyera zvemagetsi
Zvishandiso zvekuyera zvemagetsi zvakaita se galvanometers ne wattmeters zvinoshandisa musimboti we electromagnetic induction kuyera magetsi ne voltage. Semuenzaniso, galvanometer inoshandisa coil inofamba mumunda wemagineti; magetsi anokonzerwa ne induced anogadzira torque inoita kuti pointer ifambe, zvichibvumira kuyerwa kwemagetsi kwakanyatsojeka.
8. Tekinoroji yeWaya
Tekinoroji dzisina waya, kusanganisira kuchaja pasina waya uye kutaurirana pasina waya, dzinoshandisawo induction yemagetsi. Kuchaja pasina waya kunoshanda nekupinza magetsi mumudziyo unogamuchira kuburikidza nesimba remagineti rinogadzirwa nechiteshi chekuchaja. Izvi zvinobvumira kuchaja bhatiri pasina kubatana chaiko, sezvinoshandiswa mumafoni nemidziyo inopfekwa.
9. Chitima cheMaglev
Zvitima zveMaglev (magnetic levitation) zvinoshandisa musimboti we electromagnetic induction kuti zvikwire uye zvifambe pasina kubata njanji. Simba remagineti rinogadzirwa nema electromagnetic coils muchitima nenjanji rinogadzira simba rekusimudza rinobata chitima pamusoro penjanji, zvichideredza kukweshana uye zvichiita kuti kumhanya kwakanyanya kuve nesimba rakawanda.
10. MRI (Magnetic Resonance Imaging)
MRI inyanzvi yekurapa inoshandisa musimboti we electromagnetic induction kugadzira mifananidzo yakadzama yezvimiro zvemukati memuviri. Masimba emagineti akasimba nemafungu eredhiyo zvinoshandiswa kukurudzira maatomu ehydrogen mumuviri, zvichiburitsa masaini anozoshandurwa kuita mifananidzo nekombuta. MRI chishandiso chakakosha chekuongorora mukurapa kwemazuva ano.
