The Maxwell equations are a set of four fundamental equations in physics that describe how electric and magnetic fields interact. Formulated by James Clerk Maxwell in the 19th century, these equations explain how electric charges produce electric fields, how moving charges create magnetic fields, and how changing magnetic fields can induce electric currents. These equations are essential for understanding classical electromagnetism and have numerous applications, including in the design of electrical circuits, motors, and wireless communication systems. They unify the concepts of electricity and magnetism into a single framework, laying the groundwork for modern physics and technology.
