The answer is C. magnetic field poles.

The rotary part of an alternator is the magnetic field poles. The magnetic field poles are made of a ferromagnetic material, such as iron or steel. The magnetic field poles are rotated by a motor or another power source.

As the magnetic field poles rotate, they induce an electric current in the armature winding. The armature winding is a copper winding that is wrapped around a laminated iron core. The electric current that is induced in the armature winding is used to power electrical devices.

Here are some additional details about the rotary part of an alternator:

  • It is made of a ferromagnetic material, such as iron or steel.
  • It is rotated by a motor or another power source.
  • It induces an electric current in the armature winding.
  • The armature winding is a copper winding that is wrapped around a laminated iron core.
  • The electric current that is induced in the armature winding is used to power electrical devices.

The rotary part of an alternator is essential for the operation of the alternator. Without the rotary part, the alternator would not be able to generate electricity.
