Electromagnetic Field Theory
Electromagnetic Field Theory studies how electric and magnetic fields interact with charged particles, influencing their behavior. In plasma physics, it explains the dynamics of ionized gases, where both electric and magnetic fields play crucial roles. Magnetostatics focuses on static fields generated by steady currents, while electromagnetic waves describe how changing fields propagate through space, like light. Quantum Electrodynamics (QED) extends this understanding to the quantum level, explaining how light interacts with matter through particles called photons. Together, these concepts unify our understanding of electricity, magnetism, and light in both classical and quantum contexts.

Electromagnetic field theory describes how electric and magnetic forces interact and propagate through space. It explains how charged particles create electric fields, while moving charges generate magnetic fields. Together, these fields form electromagnetic waves, like light. This theory is fundamental to understanding technologies such as radios, microwaves, and even modern telecommunications. It combines principles from electricity and magnetism, unified in equations developed by James Clerk Maxwell in the 19th century, allowing us to analyze and predict how these forces affect objects and energy in our universe.
