Explanation:
Peak output voltage
V
Area of square armature 
Magnetic field
T
Angular frequency 
According to the law of electromagnetic induction,

Where
number of loops of wire.

≅ 28
Thus, 28 loops of wire should be wound on the square armature.
Positive charge=proton
Negative charge=electron
No charge/neutral=neutron
