Question

An AC generator has 80. rectangular loops on its armature. Each loop is 12. cm long and 8.0 cm wide. The armature rotates at 1200. rpm about an axis parallel to the long side. If the loop rotates in a uniform magnetic field of 0.30 T, which is perpendicular to the axis of rotation, what will be the maximum output voltage of this generator?

Answer 1

V = NBAω, where N denotes the number of loops, B is the magnetic field which passes through the armature, A is the area of each plate and ω is the angular speed. Just plug in the values :)

Answer 2

so its 29 V ?

Answer 3

80*(0.12*0.08)*0.3*1200*2π/60= 28.95. Yes, it's correct.
