[ 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 ?
