Answer
Brief Explanations:
In an electric generator, the axle rotates the armature in the magnetic - field of a permanent magnet (in some cases) or an electromagnet. According to Faraday's law of electromagnetic induction, this relative motion induces an electric current. The armature is the part where the current is induced and the axle is used to provide the mechanical rotation.
Answer:
The axle rotates the armature in the magnetic field of a permanent magnet, which induces an electric current. (First option)
