What is an electromagnetic force?
Electromagnetic force uses power for particles from the electromagnetic field. The concept produces electricity by means of changes in the magnetic field. This is most often found in systems such as electrical generators, alternating current motors and transformers. When preparing for the lecture, he noticed that the electric current of the battery caused the movement of the compass needle. It is noted that its discovery, individual unit of magnetic induction is referred to as oersted .
After Obsted's discovery, many scientists have tried to understand phenomena in what happened to scientific discipline of electrodynamics. Among the most important individuals working in the field were Andre-Marie Ampere, Michael Faraday and Heinrich Hertz. Research has shown that the electromagnetic force was responsible for almost all forms of radio radio wool to gamma rays.
Albert Einstein also investigated the electromagnetic force at the beginning of the 20th century. He assumed that the principles of electromagnetism were responsible for the photoelectric effect and the existence of photons.This meant that the existence of a magnetic field and its forces was important for almost all aspects of visible light.
Electromagnetic force is considered one of the basic forces in physics that explains the functioning of the universe. The interactions between the atoms are caused by this force electrically stimulating protons and electrons of atoms. All objects in the universe contain this basic power. In the human body, the electromagnetism of cells is responsible for allowing people to move objects. Chemically, the magnetic attraction of electrons leads to all reactions between substances.
In terms of mechanical devices, electromagnetic force is necessary for the production and use of electricity. Mechanical energy can be converted into electricity by means of induction concept. The voltage is formed by placing the conductor in the magnetic field that changes. Essentially, electricity is already in the device, it must only be stimulated by a magnetic changeof the field. As the magnetic flow changes in a closed circuit, the side effect is the stimulation of electrons, which results in electricity production.
The opposite effect of conversion of electricity into mechanical energy is also caused by electromagnetism. Drawing the engine either direct current or alternating current from the energy source converts energy. As electricity passes through the engine, the magnetic field fluctuated and creates mechanical energy.
