    Hi,

    Why is quartz considered a naturally occuring electret?

    Thanks

    Because it exhibits electret properties and because it occurs naturally :rolleyes:. Have you read this?

    Dear Alec,

    Thanks for the reply. I did read that article. So quartz exhibits a continual electic field naturally without any processes to create it?

    "Electret materials are quite common in nature. Quartz and other forms of silicon dioxide, for example, are naturally occurring electrets."


    Thanks

    A dead battery is still called a battery and an electromagnet is still called a magnet when it is not energized. Quartz is an electret material but you must apply a charge to it - and isolate it from other conductors so it does not discharge. Almost any insulator - very good insulator - can do this.

    A mechanical force can be applied to create an electric force.
    Applying an electric force produces a mechanical response.
