I Electret with circular electric field

Click For 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 'Why higher speeds need more power if backward force is the same?'

Power = Force v Speed Power of my horse = 104kgx9.81m/s^2 x 0.732m/s = 1HP =746W Force/tension in rope stay the same if horse run at 0.73m/s or at 15m/s, so why then horse need to be more powerfull to pull at higher speed even if backward force at him(rope tension) stay the same? I understand that if I increase weight, it is hrader for horse to pull at higher speed because now is backward force increased, but don't understand why is harder to pull at higher speed if weight(backward force)...
