"WebAs explained in Induced Current in a Wire, motional emf in a straight wire moving at velocity v through a magnetic field B is E = B ℓ v, where the velocity is perpendicular to the magnetic field. In the generator, the velocity makes an angle θ with B (see Figure 20.27 ), so the velocity component perpendicular to B is v sin θ. " - Equations for induction wires
