The two statements that are true about all generators are:
- They convert motion energy to electric energy.
- They use the relative motion of a magnet and a coil of wire.
The other statements may apply to specific types of generators but are not universally true for all generators. For example, not all generators are powered by fossil fuels, and they do not all have a fixed pair of magnets and a rotating metal coil; some use different configurations. Additionally, generators do not convert electric energy to motion energy; that describes a motor instead.
