Mawonekedwe ozungulira ndi chingwe cholumikizira chimapanga inductor (chingwe chozungulira mphete ya maginito chimagwiritsidwa ntchito ngati coil inductance), yomwe nthawi zambiri imagwiritsidwa ntchito pazinthu zotsutsana ndi zosokoneza zamagetsi zamagetsi ndipo zimakhala ndi chitetezo chabwino pa phokoso lapamwamba, kotero umatchedwa kuyamwa mkuwa, chifukwa chitsulo kawirikawiri ntchito Ferrite zakuthupi, tiyeni tilankhule za ferrite mikanda (apa amatchedwa mikanda yozungulira). Pamwamba pa chithunzicho ndi mphete yophatikizika ya maginito, ndipo pansi ndi mphete ya maginito yokhala ndi tatifupi. Mphete ya maginito ili ndi mawonekedwe osiyanasiyana a impedance pama frequency osiyanasiyana. Nthawi zambiri, impedance ndi yaying'ono kwambiri pama frequency otsika. Pamene ma frequency amawuka, kutsekeka kwa mphete ya maginito kumawonjezeka kwambiri. Mphamvu ya inductance imadziwika bwino. Kukwera kwa ma frequency azizindikiro, ndikosavuta kuwunikira. Nthawi zambiri, palibe wosanjikiza wotchinga pozungulira, ndipo mlongoti wokhala ndi chizindikiritso chabwino umatha kulandira ma siginecha osiyanasiyana othamanga kwambiri kuchokera kumadera ozungulira. Adasintha kufalikira kwa ma siginecha othandiza ndikusokoneza kwambiri magwiridwe antchito amagetsi, chifukwa chake kusokoneza kwamagetsi (EM) kwa zida zamagetsi kuyenera kuchepetsedwa. Pansi pakuchita kwa mphete ya maginito, ngakhale chizindikiro chodziwika bwino chikadutsa bwino, chizindikiro chosokoneza chapamwamba chikhoza kuponderezedwa bwino, ndipo mtengo wake ndi wotsika. Mtundu mphete inductance

Inductance imagwiranso ntchito yofunikira pakuteteza ma siginecha, kusefa phokoso, kukhazikika kwapano komanso kuponderezana kwamagetsi.

1. Gulu la inductance:

Zosankhidwa ndi ma frequency ogwirira ntchito

Ma inductors amatha kugawidwa kukhala ma inductors apamwamba kwambiri, ma inductors apakati pafupipafupi komanso ma inductors otsika kwambiri malinga ndi ma frequency awo ogwirira ntchito.

Ma Air-core, maginito-core ndi copper-core inductors nthawi zambiri amakhala apakati-pafupipafupi kapena ma frequency inductors, pomwe ma inductors a iron-core nthawi zambiri amakhala otsika kwambiri.
