Electromagnetism
Electromagnetism is one of the fundamental forces of nature and describes the interaction between electrically charged particles, encompassing the electric and magnetic fields. It is based on Maxwell's Equations, which unify the description of electrical and magnetic phenomena.
The main concepts include:
Electric Field: Region where an electric charge exerts a force on another charge.
Magnetic Field: Created by moving charges (electric currents) and magnets, it affects moving charged particles.
Electromagnetic Waves: Oscillations of the electric and magnetic fields that propagate in space, such as light, microwaves and radio.
Electromagnetism is essential for the functioning of several technologies, such as electronics, electrical power generation, wireless communication and medical imaging techniques (e.g. magnetic resonance imaging). It is also crucial for the understanding of light and the interactions between charged particles, being fundamental for several areas of physics and engineering.
