Without a generator, the mechanical energy that is produced by the wind turbine blades would not be able to transform into electrical energy. A coil of wire , located inside the generator, spins inside a magnetic feild caused by permanent magnets. This process produces an electromagent which is able to create an electrical current. Consequently, electrical energy is generated and can be used as a power source.
Factors that affect output
The desgin of the wind turbine is important to maximize the efficiency and ensure that the turbines are able to capture as much energy from the wind as possible.
Three Factors that greatly affect the output of the turbines are:
- Wind Speed
- Blade Size
- Angle of the Blades
As the speed of the wind increases, it is hitting the blades at a faster rate. This causes the wind turbine to spin at a faster speed, causing more energy to be produced. Conversly, when the wind speed decreases, it is hitting the blades at a slower rate, causing the wind turbine to spin at a slower speed, producing less energy.
The larger the blade size, the more force is required to cause them to spin (motion). On the other hand, the smaller the blade size, the less force is required to cause them to spin. So, this factor affects the output because if the blades are too big it will be increasingly difficult for the wind turbine to turn and generate energy.
The angle of the blades also plays a crucial role in the outcome. If the angle is incorrect the turbine will not be able to effiecently spin and will have difficulty generating electricity.

Law of Conservation of Energy
Wind turbines use the kinetic energy of the wind to generate electrical energy. This conversion is an example of the law of conservation of energy. The law states that energy can neither be created nor destroyed, only transformed from one form to another. The kinetic energy of the wind is converted into electrical energy by the wind turbine, and this energy is then used to power homes and businesses. Thus, the total energy in the system remains the same. The wind turbine simply transfers energy from one form (kinetic energy) to another (electrical energy) and no energy was created or destroyed.

A magnetic field, induces electric charge movement, which in turn produces an electrical current. Magnetic fields affect electrical current in wind turbines by causing a current to flow through the wind turbine's generator coils. This current is then used to generate electricity. The strength of the current is determined by the strength of the magnetic field, so when the magnetic field is stronger, the current is stronger, and more electricity is generated.

An electrical current in a wire generates a magnetic field around the wire. The direction of the magnetic field depends on the direction of the current. In the case of wind turbines, the electrical current produces a magnetic field, which interacts with the rotating permanent magnets in the turbine's rotor. This interaction causes the rotor to turn, which in turn spins the turbine and generates electricity.
