   Electromagnetism (Maxwell's Equations)
   The set of four governing equations for classical electromagnetism are a system of coupled PDEs. In differential form, they relate the electric field ($\mathbf{E}$) and magnetic field ($\mathbf{B}$) via divergence and curl operations, inherently describing how charges and currents generate fields, and how fields propagate through [s…
