EMF = BLv sin θ
 EMF=volts
 L = lenght
 v = velocity

EMF = Δ(BA) / Δt
 A = area
 t = time
 EMF = volts

φ = B A cos θ
φ = magnetic flux

E = E0 sin ω t
 E0 = peak output voltage
 ω = 2*pi*f = angular velocity

E0 = N A B ω
 E0 = peak output voltage
 ω = 2*pi*f = angular velocity

VP / VS =NP / NS
 V = voltage
 N = no. of turns

If NP > NS,
then the transformer is a stepdown, which reduces AC voltage.

NP < NS,
then the transformer is a stepup, which increases AC voltage.
