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