Electrodynamics
Electrodynamics is the study of how electric charges and currents interact. It shows how charges produce electric and magnetic fields, and how these fields can cause charges to move. This principle is what makes many everyday technologies function, like radios, TVs, and cellphones, which use electromagnetic waves to send information. Electrodynamics also explains how electricity flows through wires, allowing us to have power in our homes and businesses. At its core, electrodynamics is just about the give-and-take between charges and the space around them.

Electrodynamics is the branch of physics that studies the interaction between electrically charged particles and electromagnetic fields. It explains how electric and magnetic forces work together, influencing the behavior of objects in motion. This includes phenomena such as electricity flowing in wires, the generation of magnetic fields, and how light travels as electromagnetic waves. The principles of electrodynamics are fundamental to many technologies, including electric motors, radios, and even the way we communicate wirelessly. At its core, it helps us understand how electricity and magnetism shape our everyday world.
