Visualisation of electric field lines

Demonstration of electric field lines using a suspension of small particles in oil.

A voltage of 10 kV is applied to the electrodes. The plate with the electrodes is illuminated from below to make the particles responding to the electric field more visible.

A set of differently shaped electrodes and a suspension of particles in a liquid.
