sorry my earliar reply there was a mistake ignore it .

Emf in primary
E1=4.44fN1Bm
Emf in secondary
E2=4.44fN2Bm
where Bm is maximum /peak flux density, in weber /sq m
(Tesla)
under no load condition E!=v1, E2=v2 , assuming negligible
Magnetizing current.
equation is v=4.44FNBm
or say V/N= 4.44FBm
1) Thus reduction in frequency F causes the increase in
flux and their by flux density.
2) Thus increase in volt/turn , V/N causes increase in the
flux and thereby flux density.
