Near the middle of the 19th century, Scottish physicist James Clerk-Maxwell proved that magnetic and electric fields were different aspects of the same field. Maxwell also proved that the behavior of light evolved naturally from this theory and predicted its absolute velocity. The study of Electromagnetism is another very broad topic within physics. Forces that hold molecules together, how our cell phones work, and the nature of electricity are all described by electromagnetic theory. Conceptual StrandElectric change is the fundamental quantity that underlies electricity and magnetism.Guiding QuestionHow does an electric charge produce electric and magnetic fields?
