Ok, now I got another question while doing electromagnetic induction questions.

I know flux linkage=NBA and in a rotating coil, Flux linkage=NBA cos wt, which differentiated (Faraday's Law) wrt time gives E=NBAw sin wt, where w = angular frequency.

However, when the plane of the coil is parallel to the magnetic field (assuming uniform magnetic field), NBA=0 since A=0. But according to E=BLV, where B, L and V are mutually perpendicular to each other, giving rise to a emf. But according to the differentiated eqn, NBA=0, so how can E be some value?

Vice versa when the plane is perpendicular to the field. NBA=maximum, but according to E=BLV, V and B are not perpendicular, giving rise to a zero emf.

Im very confused about this, anyone can help?

Thanks.
