I Has anyone worked with electrets?

    Everyone has magnets, but I was wondering what is their electrical equivalent. OBviously an electron is charged but I can't manipulate it.

    I have found this:

    Do you know this materials? Is it possible to purchase some electrets in a store?

    Electrets are commonly used in condenser microphones.
