2. An AC generator has 80 rectangular loops on
its armature. Each loop is 11 cm long and 7 cm wide. The armature
rotates at 1100 rpm about an axis parallel to the long side. If the
loop rotates in a uniform magnetic field of 0.9 T, which is
perpendicular to the axis of rotation, what will be the
maximum output voltage of this
generator?
