# Questions tagged [maxwell-equations]

A set of four equations that define electrodynamics. They comprise the Gauss laws for the electric and magnetic fields, the Faraday law, and the Ampère law. Together, these equations uniquely determine the electric and magnetic fields of a physical system. DO NOT USE THIS TAG for the Maxwell-Boltzmann distribution, or the thermodynamical equations known as Maxwell's relations.

### Why must we reapply 0-divergence constraints in extracting valid solutions of free-space Maxwell's equations from solutions to Helmholtz equations?

--------Definitions---------- For reference: Maxwell's equations as I understand them plus definitions of $\vec{B}$ and $\vec{D}$ \begin{align} \textrm{Maxwell's curl of }\vec{E} &: \nabla\times\...

### Observing Electric and Magnetic Field Lines Around a Current Carrying Wire

Referring to the idea of using grass seeds for observing electric field near current carrying wires from the following article, https://www.ifi.unicamp.br/~assis/Found-Phys-V29-p729-753(1999).pdf I ...

### Changing Electric Field in a Capacitor

A capacitor has circular plates with radius $R$ and is being charged by a constant current $I$. The electric field $E$ between the plates is increasing, so the energy density is also increasing. This ...

### Using the electromagnetic field tensor to derive Maxwell-Faraday equation

I'm currently going through Byron and Fuller, and problem 1.13 is a problem about deriving the electromagnetic field tensor. The field tensor we derive is the complex version: F = \begin{bmatrix} 0 ...
