Physics: ELECTROMAGNETISM
Electromagnetism is defined as the attraction of different charged particles in electric and magnetic field. Electromagnetism is formed of two different words electric field and magnetic field. The study of electromagnetism can be divided into study of electrostatics that is concerned with the interaction between different charges at rest and electro dynamics.
Electromagnetism explains the motion of the charge in the presence of electric and magnetic field. A charge may move in a different way in the presence of electric field and the motion of the charge can be completely different in the presence of magnetic field. In electromagnetism, a charge is present under both the electric and magnetic field and the changes in its motion and speed are calculated and evaluated through the study of electromagnetism by using various formulas and concepts of electro dynamics.
Electromagnetism is also known as the physics applied in electromagnetic field. Electromagnetic field exerts a force on a particle that an electric charge due to which its motion and its behaviour is affected. A changing of magnetic field leads to the production of electric field.
Whenever are neutral electron enters an electric field it gains a charge. A charge electron enters into an excited state and show different behaviour as compared to its original behaviour when it was in the state of rest. That story of electromagnetism is based on Maxwell’s equation and Lorentz force. It tells when an electron enters into an excited state it starts to radiating energy in the form of heat and light.
