Do you know that every light wave, radio signal, and magnetic field follows the same set of rules? James Clerk Maxwell’s Laws, also called Maxwell’s Equations, brought together electricity and magnetism into one complete theory of electromagnetism. They describe how electric and magnetic fields behave, interact, and move through space. Before Maxwell, scientists like Faraday and Ampère had found pieces of the puzzle electricity could create magnetism, and moving magnets could create electricity.
