Background Research
A generator is a machine that converts mechanical energy into direct current electrical energy in a process explained by Faraday's law of induction.
He realized that he could concert energy used to spin the coil into electrical energy. His principle powers generators that run on gasoline or diesel fuel, as well as the massive turbines in power plants, in this case the coil are turned by falling water or stream generated by burning coal or igniting nuclear reactions. A magnetic field can be created by passing copper coils through magnates. All generators are motors working in inverse.
Materials:
Hand Crank Generator.
Introduction
The mechanical energy from cranking becomes electrical Energy
Materials
You need a hand crank generator.
procedure
First, I found a hand crank generator, then I connected with a light, I crank it twice, first time was slow cranking, and I record the data, the Second time I cranked hard and fast and we saw different in the light brightness
Scientific Principle
A hand crank generator is basically an electric motor working in reverse powered by mechanical energy.
Safety Regulations
Do not leave wires uncovered while cranking.
How it works
Two vital parts must exist in order for a dynamo to operate successfully: A stationary structure to provide a constant magnetic field and a set of rotational windings able to rotate 360° inside of the field. On smaller dynamos, such as that found in hand crank flashlights, a permanent magnet provides the constant magnetic field and a handle or interlocking twisting apparatus or even shaking the item serves as the rotational winding. Without one of these two objects, in these circumstances, it is impossible to create the necessary electric field to generate the power required to power the light bulb of the flashlight.
FARADAY'S LAW
One main principle that follows my experiment is Faraday's law. Faraday's law serves as a summary of the ways a voltage may be generated by a changing magnetic environment. Faraday's law is a fundamental relationship which comes from Maxwell's equation. The induced emf in a coil is equal to the negative of the rate of change of magnetic flux times the number of turns in the coil. It involves the interaction of charge with magnetic field
