Maxwell's Equations are a set of four fundamental equations that describe how electric and magnetic fields interact and propagate. Formulated by James Clerk Maxwell in the 19th century, these equations unify electricity, magnetism, and optics into a single theoretical framework, laying the groundwork for modern physics. These equations explain phenomena such as electromagnetic waves, which include visible light, radio waves, and X-rays. They are essential for understanding how electric charges produce electric fields, how magnetic fields are generated by moving charges, and how changing electric fields can create magnetic fields, thus illustrating the interconnected nature of electricity and magnetism.
