Electrostatic loudspeakers work by the attraction and repulsion of a thin conductive film in an electric field rather than the magnetic attraction and repulsion you’ll find in a moving-coil ...

You might have heard of electrets being used in microphones, but do you know what they are? Electrets produce a semi-permanent static electric field, similar to how a magnet produces a magnetic ...

THE description by Van Wyk and Kühn 1 of their corona motor reminded me that a number of years ago I made an electrostatic motor, in basic concept not unlike their motor, but fitted with metal ...

Magnetic force can overcome gravity. That’s why this magnet can hover in mid-air. Electrostatic force also attracts and repels objects. Rubbing the balloon on another surface creates a small ...

An electrostatic loudspeaker uses a thin plastic diaphragm residing between two perforated metal sheets (the grids or stator plates). The audio signal is applied to the grids out of phase.

A plotter that uses an electrostatic method of printing. Liquid toner models use a positively charged toner that is attracted to paper which is negatively charged by passing by a line of ...

This transparent "tape," known as an electrostatic sticker, is becoming more common in dashcam kits. Manufacturers aim to ...
