Ubwino waukadaulo wa zida zotseketsa pafupipafupi

Zida zozimitsira ma frequency apamwamba zimagwira ntchito pogwiritsa ntchito mfundo ya lamulo la electromagnetic induction, ndikutenthetsa chogwirira ntchito popanga magetsi amphamvu. Zida zozimitsa zothamanga kwambiri zimapangidwa makamaka ndi coil induction, magetsi a AC ndi workpiece. Koyiloyo imatha kusinthidwa mosavuta kuti ikwaniritse zosowa za kutentha kwa workpiece. Koyilo ya induction imapanga mphamvu ya maginito yolowera pansi pakusintha kwapano. Ngati workpiece imayikidwa mu induction magnetic field, ma elekitironi othamanga kwambiri adzapangidwa, motero amapanga mphamvu yamagetsi kuti akwaniritse cholinga cha kutentha.
