Making an Electret, or several actually.

In that article it also mentions this polarity reversal over time but they are suggesting hours rather than weeks.

Hi Grum. I don't know, but maybe the charge reversal time varies depending on the exact composition and portions
used in the electret material.

All the best...

The above is a visual representation of thermodielectric induction
The center two charges are on either side of the dielectric
The outer charges are on the conductors


While the dielectric isulative, it's surface charges conduct onto the conductor
in the same way a negative charged balloon transfers its charge onto the
objects it attracts.


There are two effects
First induction
Then conduction
(then induction again)


@void yes, Faraday said it does vary with materials

Hi Guys.

Ok, my poling mould is nearing completion and the raw materials have arrived from their various locations around the UK.

I have 500 grams of  Carnauba flakes, 500 grams of Rosin crystals and 200 grams of Beeswax. The recipe states a 45%, 45%, and 10% Beeswax by weight.

Am I correct that 100 grams of Beeswax added to the Kilogram of the other ingredients is right?

Cheers Graham.

Or you can downsize it like Webby suggests.


It is the total that you want to take the % of
