Electromagnetism
Electromagnetism is the specialized area of physics that studies the interaction between electricity and magnetism. When objects are charged electrically they produce an electromagnetic field. Examples of electromagnetic fields include ultraviolet waves, radio waves and x-rays. Electromagnetism was discovered in 1865 by James Clerk Maxwell. … Keep Reading → The works of Michael Faraday, Oliver Heaviside, and Heinrich Hertz also played a major role in the formulation of the theory of electromagnetism. Electromagnetism has many practical uses that we encounter on a regular basis. One of the most common uses is in different types of motors. Medical technology has also relied on electromagnetism, with equipment such as the CT scan machine that is used to diagnose injury and disease. The use of electromagnetism as a source of power holds great hope as a replacement for fossil fuels that are harmful to the environment.
