Electret with circular electric field

Click For Summary
SUMMARY

An electret can retain a persistent electric field, typically as a flat slab with a perpendicular field. The discussion explores the feasibility of creating an electret with a permanent circular electric field, suggesting that it could be formed rapidly around a decreasing magnetic flux. The concept raises questions about the potential magnetic properties of such electrets, including their ability to attract and repel, and the relevance of the piezoelectric effect in this context.

[ 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?
