Answer;
Magnets
In large generators in power plants, magnets rotate inside a coil of wire to produce an electric current.
Explanation;
- Generators are devices that use electromagnetic induction to convert mechanical energy to electrical energy.
- In power plants, large wheel known as turbine that rotates when pushed by steam,wind, or water and provides mechanical energy to a generator.
- Generators are used in power plants and have very large quantities of copper wire spinning around inside very large magnets, at very high speeds. A turbine spins the shaft that runs the generator. Eventually, electric current is generated.
