E-Field Apparatus

Apparatus includes electrodes, clear acrylic base with 4mm sockets to clamp electrodes and connect power supply, petri dishes and instructions.

It is constructed from transparent acrylic, which allows it to be placed on an overhead projector for class demonstrations but can also be used on a white surface for use with visualisers or for direct observation by smaller groups. 

This apparatus allows visualisation of electric fields between various electrode configurations, in a similar way to how iron filings allow visualisation of magnetic fields. 

Electric fields large enough to influence the particles, a high voltage, low current 2-5kV EHT power supply is required. 

Base dimensions (L x W x H): 150 x 150 x 65 mm.
