Electromagnetism

Overview

Electromagnetism is the combined study of electricity and magnetism, and the most important addition to classical physics after Isaac Newton's work. The concept of electromagnetism has wide applications in everyday devices such as computers, televisions, linear particle accelerators, and more. Electromagnetism operates on the fact that when electricity is run through a conductor, it produces a magnetic field, and when magnetic fields change, they produce electric fields. Because of that, as current goes on and off, magnetic fields change, which creates electric fields, which then add to the change of current. Eventually, you have a perpetual creation of electric and magnetic fields, which create electromagnetic waves, in the form of light. Because of that, you can derive the speed of light to be equal to , where is equal to the electric permittivity constant, and is equal to the magnetic permeability constant.
