🔬 Electromagnetic Theory & Fundamentals

Maxwell's Equations & Magnetism

Magnetism is fundamentally described by Maxwell's equations, which unify electricity and magnetism:

∇ × B = μ₀J + μ₀ε₀ ∂E/∂t

This shows how magnetic fields (B) are created by electric currents (J) and changing electric fields (E).
