A simple generator is used to generate a peak output voltage of 25.0 V . The square armature consists of windings that are 7.0 cm on a side and rotates in a field of 0.490 T at a rate of 60.0 rev/s . Part A How many loops of wire should be wound on the square armature

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.
