Electromagnetism
Plasma physics studies the behavior of ionized gases, or plasmas, which exhibit unique properties distinct from solids, liquids, and gases. Electromagnetism, as a fundamental aspect of plasma physics, delves into the interactions between electrically charged particles and electromagnetic fields. It investigates how moving charges generate magnetic fields, how magnetic fields influence particle motion, and how these phenomena manifest in plasmas. This subfield is crucial for understanding plasma dynamics, wave propagation, and energy transfer, all of which are essential to various applications, including fusion energy, space physics, and industrial processes involving plasmas.
