This apparatus enables electric field patterns to be shown in much the same way that magnetic fields are demonstrated with iron filings, either by direct viewing or on an overhead projector
The apparatus comprises a clear plastic dish 90 x 12mm diameter x depth, and base 140 x 125mm, which carries a pair of 4mm socket terminals / electrode holders
Alongside each terminal is a thumb screw system which permits fine height adjustment of the electrodes
Six electrodes are supplied, two 'point source', two 'line source' and two circular rings of 35 and 70mm diameter respectively
Requires an external Power Supply (B8G85458 or similar)
