The electrodynamics is the discipline which is dedicated to analyze the phenomena that generates the electricity when is in movement . These studies are oriented to the interaction of magnetic and electric fields with loads that move.
Before moving forward, remember that the electricity it is a force that arises from the presence of protons and electrons and originates from rejection or attraction between charged particles .
The behavior that these adopt particles In the electric and magnetic fields, the transmission of electromagnetic waves and the forces that are induced by variable magnetic fields are some of the issues investigated by electrodynamics, whose origins date back to the first half of the XIX century .
It is important to keep in mind that all bodies are made up of atoms or molecules , in turn composed of electrons , neutrons and protons . The electrons have an electric charge negative , the neutrons charge neutral and the protons, charge positive .
The foundation of electrodynamics is found in the movement of electrical charges that appeal to a Conductive material to move That movement gives rise to multiple phenomena and produces numerous effects that are studied by electrodynamics.
The uninterrupted passage of electrons by a driver is what is known as electric current . For this to happen, there must be a potential difference between two points of the driver. A electromotive force , meanwhile, it is necessary for the electric charges to be set in motion and a circuit , according to the principles of electrodynamics.
