Woyamba anatulukira chodabwitsa cha munthu kupatsidwa ulemu ndi Michael Faraday, kupatsidwa ulemu chodabwitsa ndi kwenikweni koyilo zakuthupi conductive (monga mkuwa). Current umayenda mwa koyilo, ndi maginito ndi kwaiye ndi kozungulira koyilo lapansi. Luso la m'munda maginito kuchita zimadalira kapangidwe koyilo ndi kuchuluka kwa panopa kudzera koyilo lapansi.
Malangizo a m'munda maginito zimadalira malangizo a pano. Choncho, kusintha malangizo a alternating panopa kudzera koyilo amachititsa malangizo a m'munda maginito kusintha, ndi mlingo wa kusintha ndi chimodzimodzi mlingo wa kusintha kwa alternating panopa. 50 Hz AC amachititsa maginito kusintha nthawi 50 kachiwiri. 400 kHz AC amachititsa maginito kusintha nthawi 400,000 mu kachiwiri.
Pamene workpiece zakuthupi conductive aikidwa mu kusintha maginito (monga maginito kwaiye ndi alternating panopa), voteji ali kwaiye mu workpiece (malamulo Faraday a). The voteji anachititsa adzabweretsa otaya ma elekitironi: izi pano! Panopa kudzera workpiece ndi zosiyana malangizo a masiku ano koyilo lapansi. Izi zikutanthauza kuti tingathe kulamulira pafupipafupi pano mu workpiece ndi kulamulira pafupipafupi pano mu koyilo lapansi.
Pamene panopa umadutsa sing'anga, kayendedwe ka ma elekitironi nkhondo kutsutsana. kukana izi ziri kuwonetseredwa ndi kutentha (Joule Kutentha zochitika). Ngakhale wamkulu kulimbikira za chuma otaya ma elekitironi monga panopa umadutsa zinthu, kutentha kwambiri ndi kwaiye, n'zothekanso kuti kutenthetsa nkhani kwambiri conductive (monga mkuwa) ntchito anachititsa panopa. zodabwitsazi ndi kofunika kwambiri chifukwa Kutentha kupatsidwa ulemu.
Kunena zoona, akonzedwa a kupatsidwa ulemu dongosolo Kutentha kuphatikizapo: magetsi,
m'ng'anjo thupi ndi madzi kuzirala gawo.
