Melcher's Law is a principle in the field of electromagnetism that describes the relationship between electric fields and magnetic fields in a moving conductor. It states that when a conductor moves through a magnetic field, an electric current is induced within the conductor. This phenomenon is a key concept in understanding how generators and motors operate. The law is named after Dr. John Melcher, who contributed to the understanding of these interactions. Melcher's Law is essential for various applications, including electric power generation and electrical engineering, as it helps explain how energy can be converted from one form to another.
