Maxwell's Equations

\begin{aligned}\nabla\cdot\mathbf{E}&=\tfrac{\rho}{\varepsilon_0} & \nabla\times\mathbf{E}&=-\tfrac{\partial\mathbf{B}}{\partial t}\\ \nabla\cdot\mathbf{B}&=0 & \nabla\times\mathbf{B}&=\mu_0\mathbf{J}+\mu_0\varepsilon_0\tfrac{\partial\mathbf{E}}{\partial t}\end{aligned}

The four equations that describe how electric and magnetic fields are generated by charges and currents, and how they interact — the complete classical theory of electromagnetism.
