Demonstrator of Dust wiping off by electrostatic

The experiment should be taken with a high-voltage power supply.

The basic structure of this demonstrator is similar to a cylindrical capacitor, Plexiglas bucket with many circle wires around outside as pole plate, and in the axis of the bucket, there is a fixed thin wire as another pole plate. The electric field between two pole plates can be calculated by using the Gaussian theorem, the formula is E=λ/2πε₀r.

By the above formula, the closer to the axis area, the stronger electricity field strength existing

Product size: 15x10x45 cm
