Questions tagged [maxwell]

James Clerk Maxwell (1831-1879) was a Scottish mathematical physicist whose most notable achievement was to formulate the classical theory of electromagnetic radiation, bringing together for the first time electricity, magnetism, and light as different manifestations of the same phenomenon.

How was the induced emf determined to be "equal" to the rate of change of flux?

Who determined, and how, the fact that the emf is exactly equal to the rate of change of flux, instead of only proportional? At first this seems like a question of units, defining the magnetic flux in ...

Who introduced Maxwell's stress tensor?

The question might be obvious, but James Clerk Maxwell did not even use vectors for his equations. Oliver Heaviside was the one that wrote them in vector form. In a paper of from 1889 "On the ...

"Équation de Maxwell-Thomson"

In French, Gauss' law for magnetism (no magnetic monopoles) is, sometimes at least, referred to as Équation de Maxwell-Thomson. What is the historical justification of this?

Why did Maxwell predict radiation pressure?

I know that Kepler thought based on comet tail that light might exert pressure (although is the Solar wind not also involved?) but did Maxwell's prediction stem from newer observations or from perhaps ...

A question concerning the history of Maxwell's equations

So I am writing my thesis around the Maxwell equations, in one part I saw to speak about their history. The issue is, I found conflicting pieces of information as to who enunciated the laws first. Let'...

Component form of the fourth Maxwell's equation

I am doing an introduction to Maxwell's equations, and it is said that originally the equations were in component form. Can anyone help with the derivation of the fourth equation? I have checked many ...

Did Maxwell discuss charge quantization?

I once read in Wikipedia that James Clerk Maxwell included the possibility that charge could be both quantified and continuous. Since the electron hadn't been discovered in 1873, does Maxwell discuss ...

How has the modelling of classical electrodynamics changed since Maxwell?

Maxwell published his Treatise on Electricity and Magnetism in 1873, 150 years ago; before the discovery of quantized charges, special relativity, quantum field theory etc. How has the mathematical ...

Validity of Maxwell's equations in the aether's reference frame

If Maxwell's equations were experimentally found on Earth such as Faradays law, coulombs law , and worked in the Earth's frame of reference, then why did people believe them to be valid in the aether'...

Did James Clerk Maxwell derive the permittivity of free space from his "Maxwell's" equations or was the parameter already known by him?

My problem is my lack of knowledge on the historical development of the constant used for the permittivity of free space. I know instead of asking the question I should read Wiki on the history of "...

What is the idea behind Maxwell's "displacement current" in electromagnetism?

I'd like to get an explanation why Maxwell chose the name "displacement current" for the term $\mu_0\epsilon_0\frac{\partial E}{\partial t}$ he added to Ampere's law (Maxwell's correction). I'm ...

How did Maxwell conclude that $\frac{\partial\bf E}{\partial t}$ was necessary to complete $c^2\nabla \times \bf B= \frac{\bf J}{\epsilon_0}\;?$

As we know $$c^2\text{curl}\;\bf B= \frac{\bf J}{\epsilon_0}$$ is incomplete & in many cases like capacitor give contradictory result against Law of conservation of charge. As Feynman writes; ...
