Electret question

  1. Jun 3, 2009 #1
    Hello :)

    Does anyone know where I can get any amount of some sort of electret material? All I find online are electret microphones...

    Also, if possible, some details about said material.

    Thank you!

    You are right; there are NO suppliers for electret materials on the web! This is very strange; I guess they are not interested in dealing with hobbyists, and will only deal with other manufacturers.

    Hi i am new to this forum. just want to find whether an electret exactly beahaves like a electric counterpart of a magnet. I mean if you hold it to a electroscope would the leaves repel each other as long as its in contact with the electret or is it just for a moment the electroscope responses. thanks in advance.
