it will be zero in first case
since the earth has magnetic field in north south direction and we know that emf=BLV where B L And V must be perpendicular to each other
and non zero is second case
since the needle is now in East West direction and thus it is perpendicular thus non zero emf
so when someone else will answer then I will mark
u will have to wait for some day
days
hmm
bye
then it will only ask you to mark
and thanks again
thanks a lot bro where are u from
