an electrical generator that produces power when rotated.

an electrical generator that produces power when rotated.

• A. Cycle
• B. Meter/Metering
• C. Magneto
• D. Fuel

Answer: (C)

The idea being tested is generating electricity through electromagnetic induction as motion provides the energy. A magneto is a self-contained generator that uses permanent magnets and windings arranged so that when the rotor turns, the magnetic flux through the windings changes. This changing flux induces voltage, producing electrical power without needing an external power source—the rotation itself drives the generation. That’s why it’s the best fit for “an electrical generator that produces power when rotated.” The other options don’t describe a generator type: a cycle refers to a repeating process or waveform, a meter is a measuring device, and fuel is simply the energy source, not a generator.
