Podle kterého z následujících vzorců lze vypočítat magnetický indukční tok protékající plochou S rovinného závitu, umístěného v magnetickém poli o magnetické indukci B rotujícího kolem jedné osy s frekvencí otáčení f (osa není shodná s osou vystupující kolmo z roviny závitu)?
Správná odpověď je: D
Magnetický indukční tok protékající plochou S rovinného závitu, který rotuje s frekvencí f v homogenním magnetickém poli o magnetické indukci B, lze spočítat podle vzorce pro magnetický indukční tok:
