Two coils ′P′'P'′P′ and ′Q′'Q'′Q′ are separated by some distance. When a current of 3A3 A3A flows through coil ′P′,'{P}^{'},′P′, a magnetic flux of 10−3Wb{10}^{-3} Wb10−3Wb passes through ′Q′.'{Q}^{'}.′Q′. No current is passed through ′Q′.'{Q}^{'}.′Q′. When no current passes through ′P′'P'′P′ and a current of 2A2 A2A passes through ′Q′,'{Q}^{'},′Q′, the flux through ′P′'P'′P′ is:
