Electromagnetic principles refer to the fundamental concepts that describe the relationship between electricity and magnetism. These principles explain how electric charges create electric fields, while moving charges generate magnetic fields. This interplay is essential for understanding how devices like motors and generators work. One key principle is Faraday's Law, which states that a changing magnetic field can induce an electric current in a conductor. Another important concept is Maxwell's Equations, which unify electricity and magnetism into a single framework. Together, these principles form the foundation for many technologies, including wireless communication and electromagnetic waves.
