Chii chinonzi Electromagnetic Induction?
Kupinza simba remagetsi (electromagnetic induction) chinhu chakakosha chemuviri chinoita kuti simba remagetsi rishandurwe kuita simba remagetsi uye zvinopesana. Pfungwa iyi yakatanga kuwanikwa naMichael Faraday naJoseph Henry mukutanga kwezana remakore rechi19, uye yakava hwaro hwematekinoroji akasiyana-siyana emazuva ano, anosanganisira majenareta emagetsi, matransformer, uye mota dzemagetsi. Chinyorwa chino chichaongorora tsananguro, misimboti yekutanga, mashandisirwo, uye kukosha kwekuisa simba remagetsi muhupenyu hwezuva nezuva.
Kunzwisisa Kugadzirwa kweElectromagnetic
Kupinza kwemagetsi kunoreva maitiro ayo simba remagineti rinoshanduka rinogadzira magetsi ari muconductor. Faraday akagadzira mutemo wekuisa magetsi mumagetsi, uyo unogona kurerutswa seizvi: "Huwandu hwemagetsi anokonzerwa mudunhu hunoenderana nekuchinja kwemagetsi anoitika munguva yakatarwa." Pamasvomhu, mutemo waFaraday unonzi:
\[ E = -\frac{d\Phi}{dt} \]
Apo \(E\) iri simba remagetsi rinoita kuti zvinhu zvishande (EMF), uye \(\Phi\) iri simba remagineti rinopinda muzvikamu zvewebers (Wb).
Nheyo dzekutanga dzeElectromagnetic Induction
Nheyo huru yekushandiswa kwemagetsi mumagetsi inogona kutsanangurwa nepfungwa dzinotevera:
1. Magnetic Flux:
Magnetic flux (\(\Phi\)) ibudiriro yesimba remagineti (B) nenzvimbo iyo simba remagineti rinopfuura napo (A), izvo zvinogona kuratidzwa seizvi:
\[ \Phi = B \cdot A \cdot \cos(\theta) \]
apo \(\theta\) iri kona iri pakati pesimba remagineti nenzvimbo.
2. Simba reElectromotive Rinokonzereswa (EMF):
Kana simba remagineti richibuda muconductor richichinja nekufamba kwenguva, simba remagetsi (EMF) richakonzereswa mu closed circuit.
3. Mutemo waLenz:
Kutungamira kwesimba rinobuda mumhepo kunogara kuri kwekuti kunopesana nekuchinja kwesimba rinobuda mumhepo. Mutemo uyu unobatsira kuona divi resimba rinobuda mumhepo uye kushandiswa kwenheyo yekuchengetedza simba.
4. Kuzvikurudzira:
Kana magetsi achichinja kuburikidza ne coil (solenoid kana inductor), anogadzira shanduko mu magnetic flux iyo inozokonzera simba re electromotive mu coil pachayo.
Mashandisirwo eElectromagnetic Induction
1. Jenareta yemagetsi:
Jenareta mudziyo unoshandura simba remakanika kuita simba remagetsi kuburikidza nekugadzirwa kwemagetsi. Mujenareta, simba remagineti rinotenderera kana kondakita rinotenderera mumunda wemagineti rinogadzira EMF, iyo inokonzera magetsi.
2. Transformer:
Matransformer anoshandiswa kuwedzera kana kuderedza voltage muAC circuits. Basa rawo rakavakirwa pa electromagnetic induction, apo AC current mu primary coil inogadzira simba remagineti rinochinja, iro rinozokonzera voltage musecondary coil.
3. Mota yeMagetsi:
Mota dzemagetsi dzinoshanda nenzira imwecheteyo semajenareta, asi nenzira yakasiyana. Magetsi anoshandiswa pa kondakita mumunda wemagineti anogadzira simba remakanika rinoita kuti pave nekutenderera.
4. Kupinza Magineti Mumahita Ekudzikisa:
Maheater e induction anoshandisa magineti anokonzerwa neAC current kuti apise zvinhu zvinofambisa mhepo. Kana simba remagineti richichinja richiburitsa ma eddy currents muzvinhu izvi, magineti aya anogadzira kupisa.
5. Biosensors neMidziyo Yekurapa:
Kushandiswa kwemagetsi mumagetsi kunoshandiswa muzvishandiso zvakasiyana-siyana zvekurapa, zvakaita seMRI (Magnetic Resonance Imaging), iyo inoona masimba emagineti anogadzirwa nenyama yemuviri wemunhu.
Kukosha Muhupenyu Hwezuva Nezuva
Chiitiko che electromagnetic induction chabatsira zvikuru muhupenyu hwedu hwemazuva ano. Heano mimwe mienzaniso chaiyo yekushandiswa kwayo muhupenyu hwezuva nezuva:
1. Sisitimu yeSimba:
Kugadzirwa kwemagetsi akawanda pasi rose kunoitwa kuburikidza nemajenareta emagetsi anogadzira magetsi, kungave kubva kumagetsi echinyakare akadai semafekitori esimba remhepo, kana simba rinogona kushandiswazve semhepo nemagetsi emvura.
2. Hupenyu hwemhuri:
Kushandiswa kwematransformer mumidziyo yakasiyana-siyana yemagetsi kunobatsira kushandura voltage yemagetsi kuti ienderane nezvinodiwa nemidziyo yemumba. Semuenzaniso, macharger efoni nelaptop anoshandisa maadapter anoshanda sematransformer madiki.
3. Kutakurwa:
Zvifambiso zvemazuva ano, zvakaita sezvitima zvinomhanya zvakanyanya, zvinoshandisa mota dzemagetsi dzinoshanda pahwaro hwe electromagnetic induction. Masisitimu ekubhureka anodzoreredza mashandiro anoshandisawo induction kushandura simba remotokari kuita simba remagetsi panguva yekubhureka.
4. Kutaurirana Pasina Waya:
Kushandiswa kwemagetsi mumagetsi kunoshandiswa muhunyanzvi hwekutaurirana husina waya hwakadai seRFID (Radio Frequency Identification) uye NFC (Near Field Communication), iyo inobvumira kutumira data pasina kubata zvakananga.
Remangwana reKugadzirwa kweMagetsi
Kugona kwekushandiswa kwemagetsi emagetsi kunoramba kuchikura nekutsvaga kutsva uye hunyanzvi. Kuferefeta kwakawanda pamusoro pezvinhu zvinogadzira simba remagetsi, izvo zvinogona kugadzira masimba emagineti akasimba pasina kurasikirwa nesimba, kunovhura mukana wekushandisa simba zvakanyanya uye kushandiswa kwakakura. Uyezve, kuvandudzwa kwetekinoroji yekutumira simba remagetsi isina waya (WPT), iyo inogonesa kuchaja michina isina waya, kunoratidza kushanduka-shanduka uye kukosha kwenheyo yekushandiswa kwemagetsi emagetsi mune ramangwana retekinoroji.
Munyaya dzekurapa, kubudirira mune nzira dzisingashandisi ma electromagnetic-based non-invasive kunogona kuvandudza kuongororwa nekurapwa kwezvirwere, zvichipa mhinduro dzakachengeteka uye dzinoshanda kune varwere.
Mhedziso
Kushandiswa kwemagetsi nemagetsi chinhu chakakosha chine mashandisirwo akawanda muminda yakasiyana-siyana yetekinoroji uye hupenyu hwezuva nezuva. Kuwanikwa nekushandiswa kwenheyo iyi kwakachinja nzira yatinogadzira, tinoshandisa, uye tinotarisira simba remagetsi. Kubva pamidziyo yemumba iri nyore kusvika kumashandisirwo emagetsi epamusoro-soro uye ekurapa, kushandiswa kwemagetsi nemagetsi kunoita basa rakakosha mukufambira mberi kwebudiriro yevanhu. Nekugona kwayo kuchiri kuongororwa, kushandiswa kwemagetsi nemagetsi kucharamba kuri chinhu chikuru chekuvandudza tekinoroji mune ramangwana.
