== <span style="color: #FFFFFF;">Remembering</span> == * '''Electrodynamics''' — The branch of physics that deals with the "Interactions" of "Electric Currents" and "Magnetic Fields." * '''Maxwell’s Equations''' — The 4 mathematical laws that describe how "Electric" and "Magnetic" fields are generated and altered by each other and by "Charges" and "Currents." * '''Electromagnetic (EM) Wave''' — A wave of "Vibrating" electric and magnetic fields that can "Travel through empty space" at the "Speed of Light." * '''Lorentz Force''' — The total "Force" exerted on a moving "Charged particle" by an electric and magnetic field. * '''Faraday’s Law''' — The discovery that a "Moving Magnet" creates an "Electric Current" (The basis of "Electric Generators"). * '''Ampère’s Law''' (with Maxwell's correction) — The discovery that an "Electric Current" creates a "Magnetic Field." * '''The Photon''' — The "Quantum Particle" of the electromagnetic field (the "Particle of Light"). * '''Gauge Theory''' — The advanced mathematical idea that the "Laws of Electrodynamics" don't change if you "Shift" the starting point of the energy (Symmetry). * '''Potential (V) and Vector Potential (A)''' — The "Hidden Fields" that are more fundamental than the "E" and "B" fields themselves. * '''Relativistic Electrodynamics''' — The realization that "Magnetism" is just "Electricity" viewed from a different "Reference Frame" (Special Relativity). </div> <div style="background-color: #006400; color: #FFFFFF; padding: 20px; border-radius: 8px; margin-bottom: 15px;">
