Have you ever heard of an Electret?

I had never heard of this until yesterday, and I feel like it's completely illogical for that to happen without purposeful repression.

An Electret, is like the opposite of a magnet. It is a material that holds a relatively permanent field. However contrary to a magnet that holds a magnetic field, an Electret is the electric version holding a permenant electric field around itself.

Electrets are made by bombarding an insulating material with electric field pulses while molten and then solidifying the material while still under the influence of the field. Similar to how magnets are created.

Electrets interact with magnetic fields, albiet at a 90° angel to a conventional magnet.

So basically, I can take an inert plastic like PTFE (Teflon) and program it to have an electric charge. And it can then interact with a magnet in a similar albiet perpendicular way that you would expect a traditional magnet to behave with another.

Why have I never heard of this? Why do we not have lightweight, frictionless PTFE plastic magnets utilised in day-to-day life?

It's a conspiracy. Electrets are underrated af

If a magnet moving through an electric field creates a charge, what does an electret moving through a magnetic field produce?

Instead of copper and neodymium, can we use PTFE and iron to build generators?

I want answers. It's a conspiracy I tells ya 🦜

I had a friend who was all over electrets and strange electric circuits ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯

It wouldn't be you by any chance lakshmana? I've seen hints of you cooking up some pretty interesting apparatus. Would love to hear more about that. I'm definitely ramping up some of my methods for alchemical happenings using things like electricity now. I've known it had an important part to play but couldn't put my finger on the button until recently.
