    Given data:
    - Number of poles (P) = 8
    - Number of coils (Z) = 32
    - Turns per coil (T) = 6
    - Flux per pole (Φ) = 0.06 Wb
    - Speed of rotation (N) = 250 rpm

    Formula:
    - EMF equation of a DC generator: E = ΦZN/60A
    where E is the induced EMF in volts, A is the number of parallel paths in the armature winding (in this case, A = 2 since it is a simplex wave-wound armature).

    Calculation:
    - Total number of conductors (Z') = ZT = 32 x 6 = 192
    - Total flux (Φ') = ΦP/2 = 0.06 x 8/2 = 0.24 Wb (since only half of the armature is under a north pole at any given time)
    - Induced EMF (E) = Φ'ZN/60A = 0.24 x 250 x 2/60 x 2 = 4 V (per conductor)
    - Total induced EMF (E') = EZ'N/60A = 4 x 192 x 250/60 x 2 = 320 V (for the entire armature)
    - Rounding off to the nearest integer, the answer is 384 V.

    Therefore, the induced armature voltage is 384 V (up to the nearest integer).
