During research in connection with the development of an electrostatic loudspeaker, an effect was discovered which led to some measurements on the attractive force between plates in a flat condenser. With the dielectric between the plates consisting of a layer of rubber dam in combination with a layer of air, the curves of attractive force vs. potential difference show a striking similarity to magnetic hysteresis curves.
