Bisa ga ka'idar shigar da lantarki ta Faraday, girman ƙarfin wutar lantarki da aka ƙirƙira a cikin na'urar ya dogara ne akan canjin canjin ƙarfin maganadisu da ke wucewa ta cikin na'urar lokacin da N-turn coil ke motsawa a cikin filin maganadisu kuma ya yanke layin ƙarfin maganadisu ( ko canjin yanayin maganadisu na filin maganadisu inda coil yake).

Firikwensin magnetoelectric mai motsi na layi

Firikwensin magnetoelectric mai motsi na madaidaiciya ya ƙunshi maganadisu na dindindin, naɗa da mahalli na firikwensin.

Lokacin da harsashi ya yi rawar jiki tare da jiki mai girgiza don auna shi kuma mitar girgiza ya fi girma fiye da yanayin yanayi na firikwensin, saboda bazara yana da laushi kuma yawan ɓangaren motsi yana da girma, ya yi latti don motsi. don girgiza (tsaya har yanzu) tare da jiki mai girgiza. A wannan lokacin, saurin motsi na dangi tsakanin maganadisu da nada yana kusa da saurin girgizar na'urar.
