Eyokuqala wathola lo mkhuba lokungeniswa umuntu UMichael Faraday, lokungeniswa mkhuba ikhoyili yezinto ezibonakalayo. conductive (ezifana nethusi) ngokuyisisekelo. Yamanje kugeleza ikhoyili, futhi kazibuthe ekhiqizwa nasezindaweni ezizungeze kwekhoyili. Ikhono kazibuthe ukwenza incike design ikhoyili kanye nenani lamanje ngokusebenzisa kwekhoyili.
I isiqondiso kazibuthe incike isiqondiso zamanje. Ngakho-ke, ushintsho isiqondiso zamanje kushintshana ngokusebenzisa ikhoyili kubangela isiqondiso kazibuthe ukushintsha, futhi ngesilinganiso ushintsho kuyafana ngesilinganiso ushintsho lwamanje kushintshana. 50 Hz AC kubangela kazibuthe ukushintsha izikhathi ezingu-50 ngomzuzwana owodwa. 400 kHz AC kubangela kazibuthe ukushintsha izikhathi 400,000 ngomzuzu owodwa.
Lapho workpiece yezinto ezibonakalayo. conductive ibekwe endaweni ekushintsheni kazibuthe (ezifana kazibuthe eyenziwe i zamanje kushintshana), zinamandla ekhiqizwa e workpiece (umthetho Faraday sika). Voltage eyenga kuzoletha ukugeleza electron: lena zamanje! Lamanje ngokusebenzisa workpiece kuyinto obuhlukile isiqondiso samanje kwekhoyili. Lokhu kusho ukuthi asikwazi ukulawula nobuningi we samanje workpiece ngokulawula ukuvama wamanje e kwekhoyili.
Lapho zamanje sidlula medium, ukuhamba electron sihlangana bangafuni. Lokhu Ukumelana livezwa ukushisa (Joule Ukushisa umphumela). Nakuba aba maningi ukumelana kwento ukugeleza electron njengoba wamanje sidlula impahla, ukushisa okwengeziwe ekhiqizwa, kungenzeka ukufudumeza impahla conductive kakhulu (ezifana nethusi) Usebenzisa zamanje eyenga. Lesi simo esiyingqayizivele sibangelwa ibaluleke kakhulu lokungeniswa bafudumale.
Ngokuvamile, iqoqo lokungeniswa bafudumale system kuhlanganise: ugesi,
esithandweni umzimba namanzi Ukupholisa ingxenye.
