Pulagi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yotchedwa electromagnetic SB1010

Mfundo yodziyimira pawokha komanso inductance

1.Electromagnetic inductor ndi gawo lamagetsi losagwira ntchito, lomwe lingasunge mphamvu zamagetsi mu mawonekedwe a maginito flux. Nthawi zambiri, wayayo imakulungidwa, ndipo ngati pali maziko apano, imayambitsa mphamvu ya maginito kuchokera kumanja kwa njira yomwe ikuyenda. Mapangidwe a electromagnetic inductor amapangidwa makamaka ndi ma coil windings, maginito pachimake ndi zida zothandizira pakunyamula. Tiyeni tiwone chomwe ma electromagnetic induction ndi kutengera kwamagetsi kwa DC electromagnetic coil.

2.Zodzipangira nokha: Pamene panopa ikudutsa pamagetsi a electromagnetic coil, mphamvu ya maginito idzapangidwanso kuzungulira koyiloyo. Pamene panopa mu koyilo imasintha, mphamvu ya maginito yozungulira imasinthanso. Kusintha kwa maginito kumeneku kumatha kupangitsa kuti koyiloyo ikhale yokha, yomwe imadzipangitsa yokha. Amatchedwa self-inductance coefficient. Nthawi zina pamakhala ma coil angapo mu induction ya electromagnetic, ndipo ma coil akakhudzana, kuyanjana kudzachitika. Kulumikizana kwa ma electromagnetic induction pakati pawo kwakhala index yolumikizirana.

3.Mutual inductance: pamene ma coil awiri a electromagnetic ali pafupi wina ndi mzake, mphamvu ya maginito ya coil imodzi yamagetsi idzasintha kupita ku 220 volt electromagnetic coil, yomwe imatchedwa mutual inductance. Mutual inductance ili mu digiri yolumikizana pakati pa ma coil awiri a electromagnetic. Zomwe zimapangidwa ndi mfundo iyi zimatchedwa ma transfoma. Ndi koyilo, amene symmetrically bala pa chatsekedwa maginito pachimake. Kuzungulira kumatembenuzidwa ndipo chiwerengero cha kutembenuka kwa koyilo ndi chimodzimodzi. Coil yodziwika bwino kwambiri yotsamwitsa imatha kupondereza kusokoneza wamba pakati pa L ndi E, koma siyingalepheretse kusokoneza kwamitundu pakati pa L ndi N.

4. Mwachidziwikire, zotsatira za maginito a electromagnetic pa conductor palokha zimatchedwa "self-induction phenomenon", ndiko kuti, kusinthika kwamakono komwe kumapangidwa ndi conductor palokha kumapanga kusintha kwa maginito, motero kumakhudza panopa mu conductor.
