Electrodynamics is the branch of physics that studies the behavior of electrically charged particles and the forces they exert on each other. It combines the principles of electricity and magnetism, focusing on how these forces interact and propagate through space. The fundamental equations governing electrodynamics are known as the Maxwell's equations, which describe how electric and magnetic fields are generated and altered by charges and currents. In electrodynamics, phenomena such as electromagnetic waves and radiation are explored, which are essential for understanding technologies like radio, television, and wireless communication. The field also plays a crucial role in various applications, including electric motors, generators, and particle accelerators, making it a vital area of study in both theoretical and applied physics.
