Kana an kuchinjana mafambiro Inopfuura nepawaya, inochinjika magineti inogadzirwa yakatenderedza waya. Iko mukati meiyo conductor yese mune inotsinhanisa magineti inoburitsa induced mafambiro. Sezvo izvi zvinokonzeresa zvazvino zvinoumba chivharo chakavharwa mukati memuitisi wese, senge mvura inovhuvhuta, inonzi Eddy current. Eddy ikozvino haingoparadzi simba remagetsi pasina, kuderedza kushanda kwekushandisa magetsi emagetsi, asiwo kukonzera kupisa kwemidziyo yemagetsi (yakadai se transformer iron core), iyo inokanganisa kushanda kwakajairika kwemidziyo mumatambudziko akaoma.
