# 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 thermodynamical equations known as Maxwell's relations.

### How to I derive the potential from a homogeneous time dependent electric field?

As the title says how can I derive the potential $V(t)$ from the following electric field given as $$E(t) = \frac{A}{\sqrt{\pi}\tau}e^{-(\frac{t}{\tau})^2}$$ Where $A$ and $\tau$ are constants.

### E and B field from Time Varying Current

How would I go about calculating the B field and E field from a time varying current charging a capacitor. Theoretically I feel like a solution should exist, but there seems to be a dependence between ...

### Deduce magnetic field based on electric field

I'm learning Maxwell's electromagnetic equations and i can't wrap my head around this problem: Given the volume $x\in [0,1], y\in [0,1], z\in [0,1]$, electric field $\vec E(x,y,z,t)$ and material ...

### An Electromagnetic Paradox?

The above diagram represents an isolated system with two masses $M$, at position $X$, and $m$, at position $x$, connected together by an extended spring. Each mass is connected by rigid rods to ...

### Do Maxwell's equations predict that electrons have no internal structure?

As far as I know, Maxwell's equations can't be derived from anything more fundamental. Does this indicate that electrons have no internal structure? I mean to say that, in my view, the entire nature ...

### What is the visualization of light according to Maxwell's theory of Electromagnetic wave? [closed]

The theory must imply a visualization. I am not being able to think or find any. I know the sine wave representation. But light obviously not goes like a physical string. right?

### What is 'velocity' in classical electrodynamics?

I have recently noticed that unless the objects in question are conducting, neutral wires, the Lorentz force law along with Maxwell's equations will give you anything and everything as a solution for ...

### About the closed line integral of electric field intensity

In electrostatics, we know that the closed line integral of electric field is zero : \oint\limits_{C} \mathbf{E}\left(\mathbf{x}\right) \boldsymbol{\cdot} \mathrm{d}\mathbf{x}=\;\;...
