I Electret with circular electric field

AI Thread Summary
An electret can theoretically be designed to maintain a permanent circular electric field, potentially formed in a slab with the field looping within its plane. This would require rapid formation around a decreasing magnetic flux, presenting challenges in its implementation. The discussion raises the possibility of such electrets exhibiting magnetic-like behavior, potentially attracting or repelling objects. Additionally, the use of the piezoelectric effect is questioned, suggesting it may not be the preferred method for creating these circular electric fields. Overall, the feasibility of creating electrets with circular electric fields remains an intriguing topic for further exploration.

[ Given that an "electret" can be made, that retains a persistent electric field, most often as a flat slab with a perpendicular field ]
Can an electret be made with a permanent circular electric field ? Eg in a slab with the field forming a loop in the plane of the slab ? It would have to be formed quickly around a decreasing magnetic flux as it decreased I guess, kind of difficult but not impossible .
Bonus question :) Would such electrets act as "magnets" ie attract and repel ?

Why don’t you use Piezoelectric effect?
 

Thread 'The Effect of Linear and Rotational Motion on Measured Weight'

Consider an extremely long and perfectly calibrated scale. A car with a mass of 1000 kg is placed on it, and the scale registers this weight accurately. Now, suppose the car begins to move, reaching very high speeds. Neglecting air resistance and rolling friction, if the car attains, for example, a velocity of 500 km/h, will the scale still indicate a weight corresponding to 1000 kg, or will the measured value decrease as a result of the motion? In a second scenario, imagine a person with a...

Thread 'Coulomb gauge implies instantaneous radial electric field?'

Scalar and vector potentials in Coulomb gauge Assume Coulomb gauge so that $$\nabla \cdot \mathbf{A}=0.\tag{1}$$ The scalar potential ##\phi## is described by Poisson's equation $$\nabla^2 \phi = -\frac{\rho}{\varepsilon_0}\tag{2}$$ which has the instantaneous general solution given by $$\phi(\mathbf{r},t)=\frac{1}{4\pi\varepsilon_0}\int \frac{\rho(\mathbf{r}',t)}{|\mathbf{r}-\mathbf{r}'|}d^3r'.\tag{3}$$ In Coulomb gauge the vector potential ##\mathbf{A}## is given by...

Thread 'Simple thought experiment with Stefan-Boltzmann law: energy'

Dear all, in an encounter of an infamous claim by Gerlich and Tscheuschner that the Greenhouse effect is inconsistent with the 2nd law of thermodynamics I came to a simple thought experiment which I wanted to share with you to check my understanding and brush up my knowledge. The thought experiment I tried to calculate through is as follows. I have a sphere (1) with radius ##r##, acting like a black body at a temperature of exactly ##T_1 = 500 K##. With Stefan-Boltzmann you can calculate...
