An electret (formed as a portmanteau of electr-from "electricity" and -et from "magnet") is a dielectric material that has a quasi-permanent electrical polarisation. An electret has internal and external electric fields, and is the electrostatic equivalent of a permanent magnet.
Electret, material that retains its electric polarization after being subjected to a strong electric field. The positive charge within the material becomes permanently displaced in the direction of the field, and the negative charge becomes permanently displaced in the direction opposite to the.
May 21, 2024 · An electret is a material that possesses a static electric field. This word is a combination of “electricity” and “magnet.” The material used in electrets is a special dielectric, an insulator with a special ability to retain a significant amount of strong electric field where it was immersed at the time of its manufacture.

An electret can be considered a piece of dielectric material with the presence of quasi-permanent real charges on the surface or in the bulk of the material, or frozen-in aligned dipoles in the bulk. An electret behaves like a battery or acts as an electrical counterpart of a permanent magnet.
An electret is a dielectric material that can retain a polarized state for a long time even in the absence of an external electric field. It is similar to a permanent magnet and can be used as a source of a permanent electric field in various applications such as microphones, phones, memory elements, and electrostatic voltmeters.
Jun 30, 2018 · An electret is like a magnet but generates a permanent electric field instead of a magnet field. T he reason why people scoff at overunity and free energy is BECAUSE IT REQUIRES THAT ENERGY MUST BE CREATED.
