Equações de Maxwell

\begin{aligned}
\nabla \cdot {\mathbf{E}} & = \frac\rho{\epsilon_0} \\
\nabla \cdot {\mathbf{B}} & = 0 \\
\nabla \times {\mathbf{E}}\, +\, \frac{\partial{\mathbf{B}}}{\partial t} & = {\mathbf{0}} \\\nabla \times {\mathbf{B}} -\, \frac1{c^2}\, \frac{\partial\mathbf{E}}{\partial t} & = \mu_0\mathbf{J}
