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 ...
“This whole field, studying electrostatic interactions between living animals, has the potential to uncover things that didn’t occur to us about how the world works.” “We know from all ...
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 ...
Electrostatic precipitators (ESPs) or electrostatic air cleaners are particulate collection devices which use electrostatic forces to separate particulate matter (PM) from exhaust gases. Electrostatic ...
