In the reference frame attached to the magnets, the electric field has a conservative circulation, and therefore: $$ \oint \mathbf{E}...

The question of whether the Maxwell–Faraday equation plays a role—that is, whether the electric field has a non-conservative...

There is a flaw in my previous argument. Using the impulse response assumes zero initial conditions, in particular that the input...

It is possible to see what happens when we replace the Heaviside echelon with a more regular entry. For simplicity, I restrict myself to...

I had not understood that the OP was specifically asking for the value at t = 0. In the general case, if one modifies the circuit in...

To be more precise, let me complete the analysis using the Laplace transform, which is very straightforward since: ##E(p) =...

This is a very classical situation when a Heaviside step is applied to a capacitor, or to an arrangement of capacitors forming a closed...

Am I missing something? Apart from scenario 2, in which the system is moved as a whole, are the others not practically feasible?

In continuum mechanics, one defines a mass-specific internal energy density by $$ e = u + \frac{1}{2}\,\rho\,v^2, $$ where...

As previously mentioned in this discussion, "heat" is a mode of energy transfer, and therefore the term "heat" is inappropriate. We...

I don't know if that answers the question. One possible answer would be that you can convert all the kinetic energy of the "cold" ball...

In continuum mechanics, one defines the vector field $$ \boldsymbol{\omega} = \frac{1}{2}\,\nabla \times \mathbf{v}. $$ It measures the...

Your mistake comes from differentiating the dipole moment as well, whereas it must be kept constant during the differentiation. To...

I received a warning message about "Unacceptable references or topics." I'm new to this site. Does this mean I have to delete the...

I prefer to pose the question this way: I have a finite charged plane and a point ##M## above the charged plane at a height ##z## much...
