Question
How does a generator create current?
- By using a magnet.
- By using a fan.
- By using energy from the sun.
- By using heat from the oil.
Hint:
When the magnets are moved near the wires or coils, they push the electrons to produce electricity.
The correct answer is: By using a magnet.
The electrical generators produce electrical energy by using magnets.
- The magnetic field creates current charges by electromagnetic induction.
- In generators, the kinetic energy is converted into electrical energy by using a magnet.
- When the magnets are moved near the wires or coils, they push the electrons and that's how produce electricity.
