The Science Behind The Electric Current!

Mainly source of electric current generated by turbines, such as wind, hydraulic, steam, and geothermal turbines, but if you don’t know the science inside the turbine, then you are in the right place.

Step # 1: Let me take you to the chemistry and physics classes.

Chemistry and physics are the core subjects to understand science among everything that depends on knowledge. The answer to the question is also hidden here, and we will explore it.

Atom: “the smallest particle of a chemical element that can exist.”

In chemistry, we dealt with atoms’ structure, where we learned neutron, proton, and electron. At the same time, we also learned that the movement of electrons from one shell to another.

Step # 2: Basic component needs to generate an electric current.

In step 1, we discussed the structure of the atom, how it works. In this step, we now jump to the material we need to generate electricity.

Coil of wire Since we know that copper is a good conductor of electricity, we need a coil of copper wire. Copper wire to generate electric current.jpg
Magnet The magnet has a large gravitational induction force to attract metal. Magnet to create magnetic field.jpg
Rotation system A rotational system means a mechanical force that allows certain things to rotate. Rotating system to provide mechanical force.jpg

Step # 3: Practical experiment of generating electrical current.

In this step, we will explore the basic concept of generating an electric current.

  • First, we attach the coil of copper wire on the shaft into a rotating system, whose axes are connected to the handle to produce mechanical force to the shaft.
  • In the second part, we put a magnet near the copper wire.
  • In the third part, we plug out two wires from the wire coil to connect the DC LED bulb.
  • Finally, we need to provide the mechanical force by the rotating system through the handle.

When we rotate the shaft, the magnet creates a magnetic field around the coil of wire. This magnetic field causes electrons’ charges to be pushed out from the coil of wire.

Conclusion: The science behind the electric current.

When a coil of wire turns around the magnet, what happens, the electrons of copper begin to move because of the magnetic field. And magnetic field force to move electrons. Once electrons move from atom-shell to LED bulb through connected to wires begins to glow. That electron particle is called an electric current.
