Explaining Faraday's Law With Lorentz Transformations of $E$ and $B$ Fields
I've searched around for this but haven't come across a totally satisfying explanation yet. I'm trying to build a relatively simple model of how the Lorentz Transformations of the $E$ and $B$ fields ...

Magnetic induction as a reletivistic effect too?
Magnetic field doesn't really exist. Magnetic attraction of two conducting wires can be explained as a relativistic effect of moving electrons with respect of stationary nuclei. Can magnetic induction ...

Is Faraday's law due to relativity ? A question from Griffith
In Griffith's EM, section 7.2.1 includes following pictures to talk about Faraday's law , where by Faraday's law I will be referring to its differential form rather than integral form.
In the images (...

Why should we expect motional emf to obey the same general relation as Faraday's Law?
There are many posts on this forum asking whether motional emf is actually an instance of Faraday's Law -- because, confusingly, it is often taught as though it is, with no qualification. The best ...

Is the current in a loop accelerating in a uniform magnetic field the same for moving and stationary observer?
By Faraday's law, a changing magnetic flux through a loop produces electromotive force $\varepsilon=-\frac{\mathrm{d}\Phi}{\mathrm{d}t}$. Suppose there is a rectangular loop in XY plane with Ohmic ...

What is the direction of the induced electric field when magnetic field moves towards wire loop?
Follow up to my previous question,
I have doubts about the direction of the induced electric field on the stationary wire loop
I thought that since the magnetic field is increasing out the page, $\...

What is the fundamental explanation for electromagnetic induction from the relativistic point of view?
Background
Faraday's law of induction gives a quantitive formula for the induced emf in a loop with changing magnetic influx through it:
$$\epsilon =-\frac{d\Phi_B}{dt}$$
Although this law is entirely ...

What exactly are relativistic fields?
Is magnetic field relativistic? Is electric field relativistic? How do you imagine something causing an actual physical difference to be purely dependent on the choice of a reference frame?

An *actual*, relativistic, intuitive explanation for inductance…?
I searched high and low, and as far as I can tell, after years, there is not a single video or site that actually explains inductance in an intuitive way.
I mean an actual explanation. Not “Faraday’s ...

How is electromagnetic induction analogous to gravitational frame dragging?
This wiki says: https://en.wikipedia.org/wiki/Frame-dragging
Qualitatively, frame-dragging can be viewed as the gravitational
analog of electromagnetic induction.
I was wondering what exactly this ...

Induced emf with no relative motion
When we change the magnetic flux encompassed by a loop, an induced current is produced. We know that the induced current is often explained with either the motion of loop with respect to the magnetic ...

Could magnetic fields really be completely substituted by relativity and electric fields?
In many textbooks (especially those for undergraduate level), magnetic fields are described merely as a relativistic side product of electric fields when considering frames in motion relative to ...

Does the Vector Potential Coil and Transformer Violate Special Relativity?
"Vector Potential Coil and Transformer" by M. Diabo et al reports the induction of voltage by a time varying curl free vector potential. A refinement reported in "Vector-Potential Coil and ...

Time varying magnetic field and faradays law of induction
According to faraday's law we say that , whenever a magnetic field varies with time it creates an "electric field" .
But I do not understand , how can a time varying magnetic field produce electric ...

On the electrodynamics of moving bodies
For if the
magnet is in motion and the conductor at rest, there arises in the neighbourhood of the magnet an electric field with a certain definite energy, producing a current at the places where ...
