Key Concepts
- Maxwell's Equations: ∇·E = ρ/ε₀, ∇×E = -∂B/∂t, ∇·B = 0, ∇×B = μ₀J + μ₀ε₀∂E/∂t
- Gauss's Law: Electric flux through surface = enclosed charge/ε₀
- Ampère's Law: Magnetic field around current-carrying wire
- Faraday's Law: Changing magnetic flux induces EMF
- Poynting Vector: S = E × H for electromagnetic power flow
- Wave Equation: ∇²E - μ₀ε₀∂²E/∂t² = 0 in vacuum
