Static Whirl

Science Caravan · Electromagnetism

Exhibit Dimensions: Transport dimensions: 540×440×640mm, Display dimensions: 540×440×1450mm. Exhibit Composition: Consists of an ABS plastic molded cabinet, ABS plastic molded pedestal, ABS milky white plastic molded operation countertop with color silk-screen flip-up instruction board, handwheel, electrostatic generator, concave spherical bowl, and protective cover. Through electromechanical interaction, it demonstrates the principles of electrostatic charge attraction and repulsion. Rotating the handwheel, the electrostatic generator applies high-voltage static electricity through a wire to the first copper foil, which becomes charged. Due to like charges repelling each other, the small ball is pushed to the next copper foil; upon contact with the second copper foil, the charge is first neutralized, then it takes on the charge of the second copper foil, and like charges repel it to the third, and so on, cyclotron accelerating.
