Kuleylka induction waxaay ku dhacdaa shey koronto ku qabanaya (ma ahan bir bir ah magnetic) marka shayga lagu meeleeyo aag kala duwan oo magnetic. Kuleylka kuleylka gudaha waxaa sabab u ah hysteresis-ka iyo luminta hada jirta.
Kuleylka induction waa habka lagu kululeeyo shey koronto ku shaqeeya (badiyaa bir ah) by urinta korontada, kuleylka kujira shayga iyadoo la adeegsanayo hada. Kuleyliyaha soo-galeyntu wuxuu ka kooban yahay elektromagnet iyo oscillator elektronik ah oo ku gudbiya ku-celcelis-badal xaadiriye ah oo hadda jira (AC) iyada oo loo marayo elektromagnet. Meesha xawaaraha ku beddelaneysa ee magnet-ka ka gashaa shayga, oo ka soo saareysa harar koronto gudaha kulaha aaladda, loo yaqaan eddy currents. Qulqulka eddu wuxuu ku socdaa iska caabbinta walaxda kuleylka ay kululeyso Joule. Qalabka ferromagnetic (iyo ferrimagnetic) sida birta, kuleylka ayaa sidoo kale laga dhalin karaa khasaaraha magnetic hysteresis. Inta jeer ee la isticmaalay waxay kuxirantahay cabirka shayga, nooca sheyga, isku-xirnaanta (inta udhaxeysa xarkaha shaqada iyo shayga la kululeynayo) iyo qoto dheer gelinta.
Dhibaatada hingisida waxay kaliya ku dhacdaa qalabka maadiga ah sida birta, nikkel, iyo kuwo kale oo yar. Khasaaridda lafdhabarta ayaa sheegaysa in tani ay keento jahwareer u dhaxeeya maaddooyinka marka la isticmaalayo maaddada hore ee jihada, ka dibna dhinaca kale. Mammogelayaasha waxaa loo tixgeliyaa inay yihiin magnets yaryar oo soo leexda iyadoo la marayo wareeg kasta oo jihada ah ee maaddada magnetic. Shaqada (tamarta) ayaa looga baahan yahay inay ku noqoto agagaarka. Tamarta tamaraysa kuleylka. Qiyaasta kharashka tamarta (korontada) waxay kordhisaa heerka korodhka (wareega).
Dhibaatooyinka hadda jira ee Eddy waxay ku dhacaan wax kasta oo wax qabad ah oo ku yaal aagag kala duwan. Tani waxay keentaa madax, xitaa haddii alaabtu aysan laheyn mid ka mid ah guryaha macdanta badanaa la xidhiidha birta iyo birta. Tusaale ahaan waa bakir, naxaas, aluminium, zirconium, birta aan la gashado, iyo uranium. Dareemayaasha Eddy waa kuwa korantada ku shaqeeya oo lagu soo rogay ficil loo yaqaan "transformer action". Magacooda ayaa tilmaamaya, waxay u muuqdaan in ay ku wareegaan wareegyada ku yaala maqaallada iyaga oo ku jira miisaan adag. Dhibaatooyinka hadda jira ee Eddy ayaa aad uga muhimsan khasaare soo noqnoqda kuleylka kuleylka. Ogsoonow in kuleylka induction waxaa lagu dabaqaa walxaha aan la taaban karin, oo aan lahayn khasaare khalkhalka ah.
Wixii kululeynta ee birta loogu talagalay adkaynta, farsamada, dhalidda, ama ujeedo kale oo u baahan heerkul ka sarreysa heerkulka Curie, kuma tiirsanaan karno qoorshaha. Dhuxulku wuxuu lumiyaa guryaha macdanta ka sarreeya heerkan. Marka birta la kululeeyo dhibicda Curie ee hoose, saamiga qorraxdu caadi ahaan waa yar tahay in la iska indho tiri karo. Dhammaan ujeedooyinka dhabta ah, I2R of the eddy currents waa habka kaliya ee tamarta korontada loo rogi karaa kuleylka ah ujeedooyinka kuleylka induction.
Labo waxyaabood oo aasaasi ah oo kuleylinta kuleylinta u dhacdo:
- Beddelaadda beerta magnetka
- Qalabka korontada ku shaqeeya ee la dhigo dhulka maadiga
